Python program to specify Number of Integers and Compute their Sum

Below is the Python program that given a list of integers, computes their SUM. The program expects a positive Integer as the Input to the “Number of integers to enter“, and exits gracefully with a custom message “The value you entered is a non-Integer!” otherwise. The program also checks if the numbers entered are positive integers and rejects any other type, requesting the user for a positive Integer instead!

#!/usr/bin/python3

numberCount = 0
total =0

upperLimit = input("How many integers do you want to enter to calculate their Sum?: ")

if upperLimit.isdigit() == True:

    upperLimit = int(upperLimit) Python program to specify Number of Integers and Compute their Sum

    print("Please enter {} positive numbers to calculate their sum! \n\n".format(upperLimit))

    while numberCount < upperLimit:
     
        number = input("Enter number:")

        if number.isdigit() == True:

            number = int(number)             

            numberCount += 1

            total += number

        else:
            print("The value you entered is a non-Integer!")

    print("\n\nYou entered {} positive numbers whose Sum is: ".format(upperLimit) + str(total) + "!")

else: 
 print("The value you entered is a non-Integer!")
