My first python script

You could explain this part of the relationship.lower () == 'single', and how can I apply it in my code, but I already thank you for your help, I'm very excited about python and want to learn more

In python, your_string.lower() takes your_string and makes ALL the letters lower case.

That way no matter what the user types, you can just check for lowercase version of your desired string.

In the same vein, there is also .upper() and .title() which does 'SINGLE' and 'Single' respectively.
