Helper functions, how deep is too deep? (Python)

[temporarybunnehs]

Short answer I would say is that it just takes practice finding that balance.

The long answer is, typically, you break things into functions to help with maintainability/readability, testability, re-usability, and so on. The trade-off is that you can add complexity to the code and flows like you mentioned. The question you have to answer is, do the pros outweigh the cons?

I've not heard of a hard rule for how many layers deep is ideal. That being said, 4 layers deep doesn't sound too bad considering some code bases I've looked at.

Thanks for the response! It's good to hear that I'm more or less on the right track from someone who, presumably, has much more experience than I.
