Adding Values - Python Programming Exercise

In this exercise, you will develop a Python program that prompts the user for an undetermined amount of numbers until the user enters 0. The program will then display the sum of the numbers entered. This task introduces you to the use of a while loop for creating dynamic programs that handle user input until a specific exit condition (in this case, entering 0) is met. By completing this exercise, you will enhance your skills in implementing repetitive processes and managing user input in Python. This type of problem-solving is essential for building interactive and flexible Python programs that can adapt to varying amounts of input and calculate dynamic results like a sum.

Adding Values

 Objective

Develop a Python program that prompts the user for an undetermined amount of numbers (until 0 is entered) and displays their sum, as follows:

Number? 5
Total = 5
Number? 10
Total = 15
Number? -2
Total = 13
Number? 0
Finished

 Example Python Exercise

 Copy Python Code 
# Initialize the total sum variable
total = 0

# Use a while loop to prompt the user for numbers until 0 is entered
while True:
    num = float(input("Number? "))
    
    # Check if the entered number is 0
    if num == 0:
        print("Finished")
        break
    
    # Add the entered number to the total sum
    total += num
    
    # Display the current total sum
    print(f"Total = {total}")

 Output

Number? 5
Total = 5
Number? 10
Total = 15
Number? -2
Total = 13
Number? 0
Finished
