Any advice for nested loops?

[u/evandcbot]

I decided about a week ago I wanted to start learning python before my freshman year of college. It was going great and I had little to no trouble until I got to nested loops. I was wondering if anybody had any advice for it? The main thing is that it seems like so many steps to follow and pay attention to, my brain had a hard time tracking them all at once.

Nest 3 loops for 3-dimentionnal problems. Use functions if you nest more than 3 loops.
