In Python I went back and forth:

I discovered list comprehension and was exited and used them a lot. Then I went to multi level list comp. Then I realise I could never debug those so went back to loops for anything needing more than a single level. Finally I discovered Generator Expression which are basically like list comp, but lazy (not evaluated) and since then I break my code in a series of generator expression which I materialise at the end with a single list comprehension. This way I keep my code readable, it's a lot cleaner then a bunch of loops, and I also benefit of Python's special optimisation for list comprehension.




I like writing generator loops with the yield statement for more complex processing.


That’s my style as well, and I followed the same path of yours!
