Continually prompting user for input in Python

Question

Objective: * Write a python program that repeatedly prompts for input of a positive number until the sum of the numbers is greater than 179. Use at least three modules/fun

Answer 1

You can repeatedly poll the number in a loop, and add the inputs into a list, e.g.

def input_numbers():
    user_inputs = []  # a list of all user's inputs
    while True:
        num = raw_input("Enter a positive integer no greater than 42 ")
        try:
            num = int(num)  # convert input string to integer
            if num <= 0:
                print "That is not a positive integer.  Try again "
            elif num > 42:
                print "The number cannot exceed 42.  Try again "
            user_inputs.append(num)
        except ValueError:  # conversion to integer may fail (e.g. int('string') ?)
            print 'Not a Number:', num

        if some_condition_regarding(user_inputs):
            break  # eventually break out of infinite while loop
