Looking for Python materials for cyber bootcamp

I am taking a Cyber bootcamp, and just lost all my Python work that I have done today (which was extensive) because my shell crashed before I took a snapshot.

I have an assessment on Python on Wednesday, and I am now starting at square one for a lot of my pre-assessment problem solving.

Besides what I already have in resources, which is ok, I am looking for something really helpful outside of where Google sends me.

Any help would be appreciated.

I feel awful that I have lost a lot because of some stupidity and bad luck.

Lesson learned, but I am feeling a bit desperate because I am still not as comfortable with Python as I am with Linux.

Thanks to anyone willing to lend a hand.
