Question

Write a Python program which calculates the average of the numbers entered by the user through the keyboard. Use an interactive loop and ask the user at each iteration if he/she wants to enter more numbers. At the end dispay the average on the screen. Using built-in library functions for finding average is not allowed.

Sample output of the program:

Enter a number > 23

More numbers (yes or no)? y

Enter a number > 4

Do you have more numbers (yes or no)? yes

Enter a number > 42

Do you have more numbers (yes or no)? yess

Enter a number > 22

Do you have more numbers (yes or no)? y

Enter a number > 33

Do you have more numbers (yes or no)? no

Average = 24.80

Answer 1

total, count = 0, 0
n = float(input("Enter a number > "))
total += n
count += 1
choice = input("More numbers (yes or no)? ")
while choice.lower() in ['y', 'yes', 'yess']:
    n = float(input("Enter a number > "))
    total += n
    count += 1
    choice = input("Do you have more numbers (yes or no)? ")
print("Average = {:.2f}".format(total / count))
