@LouisGHB that's fine, stuff like that happens sometimes. For learning python, I would use repl.it/student. Just click on the tab that says learn/teach, and there are many free programming classes available including one for python. I used this along with snakify.org, which has really comprehensive information, to learn python.
Best of luck!
