Answer:
Following are the code to this question:
userVal = input()#defining a variable userVal for input the value
x= 0#defining variable x that holds a value 0
for j in userVal:#defining for loop to count input value in number
if not(j in " .,"):#defining if block that checks there is no spaces,periods,and commas in the value
x += 1#increment the value of x by 1
print(x)#Print x variable value
Output:
Hello, My name is Alex.
17
Explanation:
In the above-given code, a variable "userVal" is defined that uses the input method for input the value from the user end, in the next line, an integer variable "x" is defined, hold value, that is 0, in this variable, we count all values.
In the next line, for loop is defined that counts string value in number and inside the loop an if block is defined, that uses the not method to remove spaces, periods, and commas from the value and increment the value of x by 1. In the last step, the print method is used, which prints the calculated value of the "x" variable.
Answer:
Explanation:#include <iostream>
#include<string>
using namespace std;
int main()
{
string str;
cout<<"Enter String \n";
getline(cin,str);/* getLine() function get the complete lines, however, if you are getting string without this function, you may lose date after space*/
//cin>>str;
int count = 0;// count the number of characeter
for (int i = 1; i <= str.size(); i++)//go through one by one character
{
if ((str[i]!=32)&&(str[i]!=44)&&(str[i]!=46))//do not count period, comma or space
{
++ count;//count the number of character
}
}
cout << "Number of characters are = "; //display
cout << count;// total number of character in string.
return 0;
}
}
Input a list of positive numbers, find the mean (average) of the numbers, and output the result. Use a subprogram to input the numbers, a function to find the mean, and a subprogram to output the result. Use a subprogram to Input the numbers, a Function to find the mean and a subprogram to output the Result.
Answer:
def inputNumber():
l = []
num = int(input("Enter the number of integers you want to enter\n"))
for i in range(0,num):
print("Enter the ", i+1, " integers ")
a = float(input())
l.append(a)
return l
def averageCalculator(l):
total = 0
for i in l:
total += i
avg = total/len(l)
return avg
def printoutput(avg):
print("The average of numbers is ", avg)
l = inputNumber()
avg = averageCalculator(l)
printoutput(avg)
Explanation:
A subprogram may be considered as a method where we pass some values in the arguments and return some value.
The answer is written in python language, where we have used
inputNumber() subprogram to get the input from the user.
function averageCalculator() to calculate the average.
printoutput() subprogram to print the output or the average of the numbers.
Please refer to the attached image for better understanding of the indentation of code.
Now, let us learn about them one by one:
inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.
Store the values in a list and return the list to the caller main program.
averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.
printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.

Write a program that reads the input.txt file character by character and writes the content of the input file to output.txt with capitalize each word (it means upper case the first letter of a word and lowercase remaining letters of the word)
Answer:
def case_convertfile( file_name):
with open(" new_file","x") as file:
file.close( )
with open("file_name", "r") as txt_file:
while True:
word = txt_file.readline( )
word_split= word.split(" ")
for word in word_split:
upper_case = word.uppercase( )
file= open("new_file","w+")
file= open("new_file","a+")
file.write(upper_case)
txt_file.close( )
file.close( )
Explanation:
This python function would open an existing file with read privilege and a new file with write and append privileges read and capitalize the content of the old file and store it in the new file.
How can technology efforts be reconciled to improve hazard/disaster preparedness, response, and mitigation to insure systems sustainability, data integrity, and supply chain protection?
Answer:
Prediction
With regard to preparedness for hazard/disaster, technology such as AI are being explored to see how they can help to predict natural disaster.
If there is a breakthrough in this space, it will drastically reduce the negative impact of natural disasters such as floods and earthquakes as people will become ready to respond to them and mitigate their effects where possible.
In agriculture, there are factors which come together to bring about flooding. Flooding is one of the major disasters which cripples entire value chains. With a potential threat anticipated or predicted by AI, businesses can invest in technologies that can help protect the farms, farmland and other resources critical to such a supply chain.
AI-powered technologies that provide prediction services often combine this advanced computing prowess with the ability to process big data.
Technology can reach places that are unreachable by humans
AI-powered robots will soon become the norm.
Presently there are self-learning and self instructing robots powered by Artificial Intelligence that have applications in warfare, manufacturing, deepsea diving and intelligence gathering, and transportation. It is not out of place to predict that in the next decade, scientists would have perfected rescue robots that can go into very unstable terrain that have been damaged by flood or earthquake and attempt a rescue of lives and property at a scale that has never been possible before.
Connectivity
Connectivity helps people access to aid, resources that are critical for survival, transmission and receipt of life--saving information etc. CISCO has successfully used its technology called TacOps (short for Tactical Operations) successfully 45 times on over 5 continents.

Individually or in a group find as many different examples as you can of physical controls and displays.a. List themb. Try to group them, or classify them.c. Discuss whether you believe the control or display is suitable for its purpose.
Answer:
Open ended investigation
Explanation:
The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.
From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions
UAAR is planning to build in house software similar to Zoom Application. University Authorities contact with you in order to provide best solution with in limited time and limited resources in term of cost.
Describe the roles, Artifacts and activities, keeping in view Scrum process model.
Compare and contract your answer with scrum over XP for development of above mention system. Justify your answer with the help of strong reasons, why you choose scrum model over XP model. How scrum is more productive for project management. Furthermore, highlight the shortcoming of XP model.
Answer:
Following are the answer to this question:
Explanation:
If working to develop Zoom-like house software, its best solution is now in a limited period of time even with effectively reduced assets;
Evaluate all roles in preparation
Create a "Pool Draw"
Choose a singular set of resources.
Utilize Time Recording.
Concentrate on assignments and project objectives.
An object, in which by-product of the development in the software. It's created for the development of even a software program. It could include database schemas, illustrations, configuration screenplays-the list just goes on.
All development activities of Scrum are composed with one or several groups from a lineout, each containing four ruck roles:
Holder of the drug
ScrumMaster and Master
Equipment for development.
Owner of the drug
It is the motivating core of the product marketing idea, that Keeps transparent the vision about what the team member is trying to seek so that to accomplish as well as interacts to all of the other members, the project manager is responsible for the success of the way to solve being formed or retained.
ScrumMaster It operates as a mentor and providing guidance throughout the development phase, it takes a leadership position in the abolishment with impediments that also impact employee productivity and therefore have no ability to control the team, but the roles of both the project team or program manager are not quite the same thing. It works as a leader instead of the management team.
Equipe for development
The Scrum characterizes the design team as a diverse, multi-functional community of individuals who design, construct as well as evaluate the application of those who want.
In this usually 5 to 9 individuals; one's representatives should be able to make quality responsive applications collaboratively.
It is a framework that operates along with teams. It is often seen as agile project management as well as explains a set of conferences, techniques, and roles that also assist individuals to organize as well as complete their employees together. The multidisciplinary team from Scrum means that a person should take a feature from idea to completion.Scrum and XP differences:
Its team members in Scrum usually operate in the various weeks with one month-long incarnation. The XP teams generally work in incarnations which are either one two weeklong. Scrum doesn't write a prescription the certain project management; XP seems to do. Scrum may not make access to other their sprints. XP teams are far more receptive to intervention inside of their repetitions.Bharath has made a table of content for his document in Open Office, in which he wants to make few changes, but he is unable to make the changes. Give reason. Explain how he can make the necessary changes
Answer:
H cannot update it because it is probably protected.
If you cannot click in the table of contents, it is probably because it is protected. To disable this protection, choose Tools > Options > OpenOffice.org Writer > Formatting Aids, and then select Enable in the Cursor in protected areas section. If you wish to edit the table of contents without enabling the cursor, you can access it from the Navigator.
Explanation:
. To update a table of contents when changes are made to the document:
Right-click anywhere in the TOC.
From the pop-up menu, choose Update Index/Table. Writer updates the table of contents to reflect the changes in the document.
You can also update the index from the Navigator by right-clicking on Indexes > Table of Contents1 and choosing Index > Update from the pop-up menu.
A computer uses a programmable clock in square-wav e mode. If a 500 MHz crystal is used, what should be the value of the holding register to achieve a clock resolution of (a) a millisecond (a clock tick once every millisecond)
Answer:
500,000
Explanation:
A computer uses a programmable clock in square-wave mode. If a 500 MHz crystal is used, what should be the value of the holding register to achieve a clock resolution of (a) a millisecond (a clock tick once every millisecond)
1 millisecond = 1 million second = 1,000,000
For a 500 MHz crystal, Counter decrement = 2
Therefore value of the holding register to a clock resolution of 1,000,000 seconds :
1,000,000/2 = 500,000
Implement the generator function scale(s, k), which yields elements of the given iterable s, scaled by k. As an extra challenge, try writing this function using a yield from statement!
def scale(s, k):
"""Yield elements of the iterable s scaled by a number k.
>>> s = scale([1, 5, 2], 5)
>>> type(s)
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
Answer:
The generator function using yield from:
def scale(s, k):
yield from map(lambda x: x * k, s)
Another way to implement generator function that works same as above using only yield:
def scale(s, k):
for i in s:
yield i * k
Explanation:
The complete program is:
def scale(s, k):
"""Yield elements of the iterable s scaled by a number k.
>>> s = scale([1, 5, 2], 5)
>>> type(s)
<class 'generator'>
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
yield from map(lambda x: x * k, s)
If you want to see the working of the above generator function scale() as per mentioned in the above comments, use the following statements :
s = scale([1, 5, 2], 5)
print(type(s))
#The above print statement outputs:
#<class 'generator'>
print(list(s))
#The above print statement outputs a list s with following items:
#[5, 25, 10]
The function def scale(s, k): is
def scale(s, k):
yield from map(lambda x: x * k, s)
This function takes two parameters i.e. s and k and this function yields elements of the given iterable s, scaled by k.
In this statement: yield from map(lambda x: x * k, s)
yield from is used which allows to refactor a generator in a simple way by splitting up generator into multiple generators.
The yield from is used inside the body of a generator function.
The lambda function is a function that has any number of arguments but can only have one expression. This expression is evaluated to an iterable from which an iterator will be extracted. This iterator yields and receives values to or from the caller of the generator. Here the expression is x: x * k and iterable is s. This expression multiplies each item to k.
map() method applies the defined function for each time in an iterable.
The generator function can also be defined as:
def scale(s, k):
for i in s:
yield i * k
For the above example
s = scale([1, 5, 2], 5)
def scale(s,k): works as follows:
s = [1, 5, 2]
k = 5
for loop iterates for each item i in iterable s and yields i*k
i*k multiplies each element i.e 1,5 and 2 to k=5 and returns a list
At first iteration, for example, i*k = 1 * 5 = 5, next iteration i*k = 5*5 = 25 and last iteration i*k = 2*5 = 10. So the output. So
s = scale([1, 5, 2], 5) In this statement now s contains 5, 25 and 10
print(list(s)) prints the values of s in a list as: [5, 25, 10] So output is:
[5, 25, 10]
Given an array of integers check if it is possible to partition the array into some number of subsequences of length k each, such that:
Each element in the array occurs in exactly one subsequence
For each subsequence, all numbers are distinct
Elements in the array having the same value must be in different subsequences
If it is possible to partition the array into subsequences while satisfying the above conditions, return "Yes", else return "No". A subsequence is formed by removing 0 or more elements from the array without changing the order of the elements that remain. For example, the subsequences of [1, 2, 3] are D. [1], [2], [3]. [1, 2], [2, 3], [1, 3], [1, 2, 3]
Example
k = 2.
numbers [1, 2, 3, 4]
The array can be partitioned with elements (1, 2) as the first subsequence, and elements [3, 4] as the next subsequence. Therefore return "Yes"
Example 2 k 3
numbers [1, 2, 2, 3]
There is no way to partition the array into subsequences such that all subsequences are of length 3 and each element in the array occurs in exactly one subsequence. Therefore return "No".

Answer:
The file can be read only by a user with the decryption key
Explanation:
The way encryption works is it scrambles the data in a file following the rules of the encryption algorithm using a certain key to tell it how to scramble everything.
Without the key, the computer doesn't know how to decrypt it.
This is true no matter who has access to the file, be it a system administrator, a hacker, or even a legitimate user who has somehow lost access to the key
Strictly speaking, encryption can be broken, but, especially with modern encryption, that's a matter of centuries, and isn't really feasible
The statement that is true of an encrypted file is that The file can be read only by a user with the decryption key.
What is decryption key?A decryption key is known to be a key that is given to Customers by a specific Distributor.
This key allows Customers to open and access the Software that they bought. The decryption key is a mechanism that permit that a file can be read only by a user.

Generating a signature with RSA alone on a long message would be too slow (presumably using cipher block chaining). Suppose we could do division quickly. Would it be reasonable to compute an RSA signature on a long message by first finding what the message equals (taking the message as a big integer), mod n, and signing that?
Answer:
Following are the algorithm to this question:
Explanation:
In the RSA algorithm can be defined as follows:
In this algorithm, we select two separate prime numbers that are the "P and Q", To protection purposes, both p and q combines are supposed to become dynamically chosen but must be similar in scale but 'unique in length' so render it easier to influence. Its value can be found by the main analysis effectively.
Computing N = PQ.
In this, N can be used for key pair, that is public and private together as the unit and the Length was its key length, normally is spoken bits. Measure,
[tex]\lambda (N) = \ lcm( \lambda (P), \lambda (Q)) = \ lcm(P- 1, Q - 1)[/tex] where [tex]\lambda[/tex] is the total function of Carmichaels. It is a privately held value. Selecting the integer E to be relatively prime from [tex]1<E < \lambda (N)[/tex]and [tex]gcd(E, \lambda (N) ) = 1;[/tex] that is [tex]E \ \ and \ \ \lambda (N)[/tex]. D was its complex number equivalent to E (modulo [tex]\lambda (N)[/tex] ); that is d was its design multiplicative equivalent of E-1.
It's more evident as a fix for d provided of DE ≡ 1 (modulo [tex]\lambda (N)[/tex] ).E with an automatic warning latitude or little mass of bigging contribute most frequently to 216 + 1 = 65,537 more qualified encrypted data.
In some situations it's was shown that far lower E values (such as 3) are less stable.
E is eligible as a supporter of the public key.
D is retained as the personal supporter of its key.
Its digital signature was its module N and the assistance for the community (or authentication). Its secret key includes that modulus N and coded (or decoding) sponsor D, that must be kept private. P, Q, and [tex]\lambda (N)[/tex] will also be confined as they can be used in measuring D. The Euler totient operates [tex]\varphi (N) = (P-1)(Q - 1)[/tex] however, could even, as mentioned throughout the initial RSA paper, have been used to compute the private exponent D rather than λ(N).
It applies because [tex]\varphi (N)[/tex], which can always be split into [tex]\lambda (N)[/tex], and thus any D satisfying DE ≡ 1, it can also satisfy (mod [tex]\lambda (N)[/tex]). It works because [tex]\varphi (N)[/tex], will always be divided by [tex]\varphi (N)[/tex],. That d issue, in this case, measurement provides a result which is larger than necessary (i.e. D > [tex]\lambda (N)[/tex] ) for time - to - time). Many RSA frameworks assume notation are generated either by methodology, however, some concepts like fips, 186-4, may demand that D< [tex]\lambda (N)[/tex]. if they use a private follower D, rather than by streamlined decoding method mostly based on a china rest theorem. Every sensitive "over-sized" exponential which does not cooperate may always be reduced to a shorter corresponding exponential by modulo [tex]\lambda (N)[/tex].
As there are common threads (P− 1) and (Q – 1) which are present throughout the [tex]N-1 = PQ-1 = (P -1)(Q - 1)+ (P-1) + (Q- 1))[/tex], it's also possible, if there are any, for all the common factors [tex](P -1) \ \ \ and \ \ (Q - 1)[/tex]to become very small, if necessary.
Indication: Its original writers of RSA articles conduct their main age range by choosing E as a modular D-reverse (module [tex]\varphi (N)[/tex]) multiplying. Because a low value (e.g. 65,537) is beneficial for E to improve the testing purpose, existing RSA implementation, such as PKCS#1, rather use E and compute D.

This aspect of cyber attacks or fraud is called phishing, whereby clients or users are questioned for personally identifiable information about them.Attackers could very well-currently the most frequently use phishing emails to exchange malicious programs that could operate effectively in what seems like several different ways. Others would get victims to steal user credentials including payment details.If the processor has 32 address lines in its address bus; i.e. 32-bit address range, what is its address space or range; i.e. what is the smallest and largest address that can be represented
Answer:
The answer is "0 to 4294967295"
Explanation:
Given bit:
32 bits
Calculating smallest and largest bits:
In any processor, it works only on the 0 and 1 bit and it also stores 0 and 1 values. so, the smallest address in bit value is= 0 and the largest bit value can be defined as follows:
largest address value in bits:
[tex]\Longrightarrow 2^{32}-1\\\\\Longrightarrow 4294967296 -1\\\\\Longrightarrow 4294967295\\\\[/tex]
smallest address= 0
largest address = 4294967295
Write a program that reads in your question #2 Python source code file and counts the occurrence of each keyword in the file. Your program should prompt the user to enter the Python source code filename
Answer:
Here is the Python program:
import keyword #module that contains list of keywords of python
filename = input("Enter Python source code filename: ") # prompts user to enter the filename of a source code
code = open(filename, "r") # opens the file in read mode
keywords = keyword.kwlist #extract list of all keywords of Python and stored it into keywords
dictionary = dict() #creates a dictionary to store each keyword and its number of occurrence in source code
for statement in code: # iterates through each line of the source code in the file
statement = statement.strip() # removes the spaces in the statement of source code
words = statement.split(" ") #break each statement of the source code into a list of words by empty space separator
for word in words:# iterates through each word/item of the words list
if word in keywords:#checks if word in the code is present in the keywords list of Python
if word in dictionary: #checks if word is already present in the dictionary
dictionary[word] = dictionary[word] + 1 #if word is present in dictionary add one to the count of the existing word
else: #if word is not already present in the dictionary
dictionary[word] = 1 #add the word to the dictionary and set the count of word to 1
for key in list(dictionary.keys()): #iterates through each word in the list of all keys in dictionary
print(key, ":", dictionary[key])# prints keyword: occurrences in key:value format of dict
Explanation:
The program is well explained in the comments attached with each line of the program.
The program prompts the user to enter the name of the file that contains the Python source code. Then the file is opened in read mode using open() method.
Then the keyword.kwlist statement contains the list of all keywords of Python. These are stored in keywords.
Then a dictionary is created which is used to store the words from the source code that are the keywords along with their number of occurrences in the file.
Then source code is split into the lines (statements) and the first for loop iterates through each line and removes the spaces in the statement of source code .
Then the lines are split into a list of words using split() method. The second for loop is used to iterate through each word in the list of words of the source code. Now each word is matched with the list of keywords of Python that is stored in keywords. If a word in the source code of the file is present in the keywords then that word is added to the dictionary and the count of that word is set to 1. If the word is already present in the dictionary. For example if there are 3 "import" keywords in the source code and if 1 of the import keywords is already in the dictionary. So when the second import keyword is found, then the count of that keyword is increased by 1 so that becomes 2.
Then the last loop is used to print each word of the Python that is a keyword along with its number of occurrences in the file.
The program and its output is attached in a screenshot. I have used this program as source code file.

Develop a CPP program to test is an array conforms heap ordered binary tree. This program read data from cin (console) and gives an error if the last item entered violates the heap condition. Use will enter at most 7 numbers. Example runs and comments (after // ) are below. Your program does not print any comments. An output similar to Exp-3 and Exp-4 is expected.
Exp-1:
Enter a number: 65
Enter a number: 56 // this is first item (root,[1]) in the heap three. it does not violate any other item. So, no // this is third [3] number, should be less than or equal to its root ([1])
Enter a number: 45 // this is fourth number, should be less than or equal to its root ([2])
Enter a number: 61 // this is fifth number, should be less than or equal to its root ([2]). It is not, 61 > 55. The 61 violated the heap.
Exp-2:
Enter a number: 100
Enter a number: 95 1/ 95 < 100, OK
Enter a number: 76 // 76 < 100, OK
Enter a number: 58 // 58 < 95, OK
Enter a number: 66 1/ 66 < 95, OK
Enter a number: 58 // 58 < 76, OK
Enter a number: 66 // 66 < 76, OK
Exp-3:
Enter a number: -15
Enter a number: -5
-5 violated the heap.
Exp-4:
Enter a number: 45
Enter a number: 0
Enter a number: 55
55 violated the heap.
Answer:
Following are the code to this question:
#include<iostream>//import header file
using namespace std;
int main()//defining main method
{
int ar[7];//defining 1_D array that stores value
int i,x=0,l1=1,j; //defining integer variable
for(i=0;i<7;i++)//defining for loop for input value from user ends
{
cout<<"Enter a Number: ";//print message
cin>>ar[i];//input value in array
if(l1<=2 && i>0)//using if block that checks the array values
{
x++;//increment the value of x by 1
}
if(l1>2 && i>0)//using if block that checks the array values
{
l1=l1-2;//using l1 variable that decrases the l1 value by 2
}
j=i-x;//using j variable that holds the index of the root of the subtree
if(i>0 && ar[j]>ar[i])// use if block that checks heap condition
{
l1++; //increment the value of l1 variable
}
if(i>0 && ar[j]<ar[i])// using the if block that violate the heap rule
{
cout<<ar[i]<<" "<<"Violate the heap";//print message with value
break;//using break keyword
}
}
return 0;
}
Output:
1)
Enter a Number: -15
Enter a Number: -5
-5 Violate the heap
2)
Enter a Number: 45
Enter a Number: 0
Enter a Number: 55
55 Violate the heap
Explanation:
In the above-given C++ language code, an array "ar" and other integer variables " i,x,l1, j" is declared, in which "i" variable used in the loop for input values from the user end.In this loop two, if block is defined, that checks the array values and in the first, if the block it will increment the value of x, and in the second if the block, it will decrease the l1 value by 2.In the next step, j variable is used that is the index of the root of the subtree. In the next step, another if block is used, that checks heap condition, that increment the value of l1 variable. In the, if block it violate the heap rule and print its values.The fact that the speed of a vehicle is lower than the prescribed limits shall relieve the driver from the duty to decrease speed when approaching and crossing an intersection. True or false
Explanation:
the answer is false ........
The fact that the speed of a vehicle is lower than the prescribed limits shall relieve the driver from the duty to decrease speed when approaching and crossing an intersection is not true.
What is intersection in the traffic rules?An intersection serves as the point where many lanes cross on the road which is a point where driver is required to follow the traffic rules.
However, the above statement is not true because , a driver can decide not decrease speed when approaching and crossing an intersection, even though it is a punishable offense in traffic rules.

fruit_t otherFruit = BLUEBERRY;
compareFruit(myFruit, otherFruit);
return 0;
What is the output?
Answer:
The output is "a pineapple is larger than a blueberry ".
Explanation:
In the given C language code Enum, typedef, and two methods "printfruit and compareFruit" is declared, that can be defined as follows:
In the enum "fruit_tag" there are multiple fruit name is declared that use as the datatypes. In the next line, the typedef is defined, that enum to define another datatype that is "fruit_t". In the next step, the printFruit method is defined that accepts "myFruit" variable in its parameter and use the switch case to to check value. In the "compareFruit" method, it accepts two parameters and uses the if-else block to check its parameters value and print its value. In the main method, two variable "myFruit and otherFruit" variable is declared that stores the values and pass into the "compareFruit" method and call the method.CHALLENGE ACTIVITY 3.7.2: Type casting: Reading and adding values.
Assign totalowls with the sum of num_owls A and num_owls_B.

3. num_owls A - input
4. num_owls_B - input
5.
6. " Your solution goes here
7.
8. print("Number of owls:', total_owls)
Answer:
total_owls = 0
num_owls_A = int(input())
num_owls_B = int(input())
total_owls = num_owls_A + num_owls_B
print("Number of owls:", total_owls)
Explanation:
Initialize the total_owls as 0
Ask the user to enter num_owls_A and num_owls_B, convert the input to int
Sum the num_owls_A and num_owls_B and set it to the total_owls
Print the total_owls
avg_owls=0.0
num_owls_zooA = int(input())
num_owls_zooB = int(input())
num_owls_zooC = int(input())
num_zoos = 3
avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos
print('Average owls per zoo:', int(avg_owls))
There is a problem while you are trying the calculate the average owls per zoo.
As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos
Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)

You bought a monochrome laser printer two years ago. The printer has gradually stopped feeding paper. Which printer component should you check first
Answer:
Pick up roller
Explanation:
you should first check the pickup roller component. This component is the part of the printer that picks paper up from the paper tray. The pickup roller links the printer and the paper. When the printer printer is running, the roller would take paper from the paper tray for the printer to print on. One of the issues it can have is Paper jam where the roller would stop turning so that it will no longer be picking papers up from the tray.
