'int' object has no attribute 'output'

This may be a silly question. I just created a function that divide a number and give remainder if the number is even else do some other mathematical operations in python.

def collataz(number):
    if number % 2 == 0:
        output = number // 2
        return int(output)

    else:
        output = 3 * number + 1
        return int(output)

import sys

try:
    c = collataz(int(input("Enter int")))
    while c.output != 1:
        print(c)
except KeyboardInterrupt:
    sys.exit()

But when I run this code it gives this following error after asking for input 'int' object has no attribute 'output' how can I fix this? and please also tell the reason why my code give this error so I can understand the problem. Please tell if something is not clear.

Thanks,

Solution

The name output inside your collatz function does not have any meaning outside of it. The value you return is just an int, which you're assigning to the name c.

I think you want the last part of your code to be something like:

    c = int(input("Enter int"))
    while c != 1:
        c = collataz(c)
        print(c)
