Making a collatz program automate the boring stuff

Question

I\'m trying to write a Collatz program using the guidelines from a project found at the end of chapter 3 of Automate the Boring Stuff with Python. I\'m using python 3.

Answer 1

Nuncjo got the solution that works. I tweaked it a little to add try and except statements for error handling.

def collatz(number):
    if number % 2 == 0:
        print(number // 2)
        return number // 2

    elif number % 2 == 1:
        result = 3 * number + 1
        print(result)
        return result

try:
    n = input("Enter number: ")
    while n > 0 and n!= 1:
        n = collatz(int(n))
except ValueError:
    print('whoops, type an integer, bro.')
