Question

Write a program that prompts the user to enter a length in feet and inches and outputs the equivalent length in centimeters. If the user enters a negative number or a nondigit number, throw and handle an appropriate exception and prompt the user to enter another set of numbers. Using Python

Answer 1

feet = input("Enter feet: ")
if(not feet.isnumeric()):
    print("Input should be a positive number")
else:
    feet = float(feet)
    if(feet < 0):
        print("Input should be a positive number")
    else:
        inch = input("Enter inch: ")
        if (not inch.isnumeric()):
            print("Input should be a positive number")
        else:
            inch = float(inch)
            if (inch < 0):
                print("Input should be a positive number")
            cm = feet*30.48 + inch*2.54
            print("Centimeters:",cm)
