12.23 Prog Assignment 4 - 2: Sum and Average

Download the temp file.

Write and test the program using IDLE or PyCharm.

Then upload it here for testing and submission.

Create a Python program (sum_and_average.py) that prompt the user to input numbers (all int) then calculate the sum and average of the entered numbers. The number of the entered numbers is n, meaning, the user can enter as many numbers as he/she wants. To finish entering numbers and calculate sum and average, the user needs to enter 0.

Hint: Use a While loop to prompt the user.

You will complete this program in several steps. For each of the following steps, end the program's output with a newline.

(1) Print the instruction once the program start running. (Submit for 1 point)

Input some integers to calculate their sum and average. Input 0 to exit. 

(2) Prompt the user to input numbers. The program should allow the user to input numbers, untill the user input 0. (Submit for 6 points, so 7 points total)

Input some integers to calculate their sum and average. Input 0 to exit. Enter a number: 5 Enter a number: 12 Enter a number: 9 Enter a number: 0 

(3) After the user input 0, the program should output the sum and average of the entered numbers. (Submit for 2 points, so 9 points total)

Input some integers to calculate their sum and average. Input 0 to exit. Enter a number: 5 Enter a number: 12 Enter a number: 9 Enter a number: 0 The Sum of the above numbers is: 26.0 The Average of the above numbers: 8.67 

(4) What if the user entered 0 for the first number? In this case, the program should inform the user that no numbers entered then exit the program. (Submit for 1 points, so 10 points total)

Input some integers to calculate their sum and average. Input 0 to exit. Enter a number: 0 You did not enter any numbers!
