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

def cyclic(number):
    if number % 2 == 0:
        if number // 2 == 1:
            print(1)
        else:
            print(number//2)
            cyclic(number // 2)
    else:
        print((number * 3) + 1)
        cyclic((number * 3) + 1)


print("Enter a number:")
try:
    n = int(input())
    cyclic(n)
except ValueError:
    print("Unvalied value")

The simplest one
