Program 3 - Write a python program that asks user to enter series of positive numbers   (the user should enter a negative number to signal the end of series) and the program should display numbers in order and their sum 

Source Code

# Initializing an empty list to store positive numbers
numbers = []

# Loop to take input from the user
while True:
    num = int(input("Enter a positive number (or a negative number to end the series): "))
    if num < 0:
        break  # Break the loop if a negative number is entered
    numbers.append(num)

# Displaying the entered numbers
if len(numbers) > 0:
    print("Entered numbers:", sorted(numbers))
    # Calculating and displaying the sum of the entered numbers
    print("Sum of the numbers:", sum(numbers))
else:
    print("No positive numbers were entered.")

OUTPUT:

Enter a positive number (or a negative number to end the series): 5
Enter a positive number (or a negative number to end the series): 6
Enter a positive number (or a negative number to end the series): 3
Enter a positive number (or a negative number to end the series): 16
Enter a positive number (or a negative number to end the series): 10
Enter a positive number (or a negative number to end the series): -1
Entered numbers: [3, 5, 6, 10, 16]
Sum of the numbers: 40
