Welcome!

Is this a homework assignment? It's okay to ask for help with those, but
we're not going to do the work for you.

There is a built-in function to do that. Have you completed the Python
tutorial <URL:https://docs.python.org/3/tutorial/>?

You may also want to participate in the ‘tutor’ forum for Python
<URL:https://mail.python.org/mailman/listinfo/tutor> which is
specialised to help beginners in Python.
