Program not calling the input

Hi, I have being trying to use the same loggic for a validation of a yes or no question but, the input is just not running, I'm not sure if i need something else to make the code run automatically.

def choice(self):
    choice = input("[Y] or [N]o").upper()

    if choice in 'YN':
        if choice == 'Y':
            print("\n\n\n\t\t\t\tIt Works!!!!!")
        else:
            print("\n\n\n\t\t\t\tIt still works!!!!!")
    else:
        return self.choice()

[MOD: added ```python formatting -cf]

What class is this method part of? How are you instantiating it and calling this method?

Are you doing something like this?

this_inst = SomeModel()
this_inst.choice()

If you wanted it to be a standalone function, save the following to a file called choise.py:

def choice():
    choice = input("[Y] or [N]o").upper()

    if choice in 'YN':
        if choice == 'Y':
            print("\n\n\n\t\t\t\tIt Works!!!!!")
        else:
            print("\n\n\n\t\t\t\tIt still works!!!!!")
    else:
        return choice()

# python idiom to execute if file called directly from command line
if __name__ == '__main__':
    # call function
    choice()

Then, at a shell prompt, type python choice.py

That might be my problem,that is all I wrote. I did it as a test, because I found it interesting the idea of making a validation test with a simple replacement for the 'C' "switch" function. I'm not sure what more do I need.

added code to answer for running the file directly.
