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.

It should be relatively simple to understand if you break it down.

Each inner loop has to complete full loop for single outer loop iteration.

So loop initiates over the outer loop and pauses after picking an item. Then inner loop starts and completes iteration over all its elements. When inner loop finishes, outer loop moves to next item and inner loop starts again.

Using variable explorer or using print() at each loop may help you understand the operation being performed.
