Question

Problem 1

Write a Python program to do the following:

(A) Ask the user to enter as many integers from 1 to 10 as he/she wants. Store the integers entered by the user in a list. Every time after the user has entered an integer, use a yes/no type question to ask whether he/she wants to enter another one.

(B) Display the list.

(C) Calculate and display the average of the integers in the list.

(D) If the average is higher than 7, subtract 1 from every number in the list. Display the modified list.

The following is an example:

Enter an integer from 1 to 10: 5

Enter another integer? [y/n] y

Enter an integer from 1 to 10: 8

Enter another integer? [y/n] y

Enter an integer from 1 to 10: 9

Enter another integer? [y/n] y

Enter an integer from 1 to 10: 7

Enter another integer? [y/n] y

Enter an integer from 1 to 10: 8

Enter another integer? [y/n] n

Number list: [5, 8, 9, 7, 8]

Average: 7.4

Modified number list: [4, 7, 8, 6, 7]

Answer 1

Hi,

The following is the code to read integers from the user, calculate the average and then display the modified list.

I have added comments in the code for your reference.

Please refer to the attached output and screenshot at the end of this answer.

## File: prog.py
def main():

#List to hold the input integers
input_list = []

#Query A
#Loop until we read all the integer inputs from the user
while True:
value = input("Enter an integer from 1 to 10: ")
input_list.append(int(value))

choice = input("Enter another integer? [y/n]: ")
if choice == 'n':
break
  
#Query B
#Print the contents of the list
print("Number List: " + str(input_list))

#Query C
#Calculate the sum and then the Average
sum = 0
for i in input_list:
sum += i

avg = sum / len(input_list);
print("Average: " + str(avg))

#Query D
#If Avg > 7, subtract 1 from each element in the list and then display
if avg > 7:
for i in range(0, len(input_list)):
input_list[i] = input_list[i] - 1

print("Modified List: " + str(input_list))   

if __name__ == "__main__":
main()
