Question

USING PYTHON - Write a program that calls a function that prompts the user to enter a real number. The function should verify that the user entered a valid real number, and should prompt the user to re-enter any invalid input. After a valid real number has been entered, the function should return the number as a number. To test your function, from a main function, call the function two separate times and print the sum of the two numbers returned. Note: Your function must be robust enough to handle all types of input including alphabetic characters without "blowing up".

Answer 1

def get_real_number():
    while True:
        try:
            return float(input("Enter a real number: "))
        except ValueError:
            print("Invalid input")


def main():
    n1 = get_real_number()
    n2 = get_real_number()
    print("Sum", n1+n2)


main()
