Currently, list.reverse() only works for an entire list. If one wants to
reverse a section of it 'in-place', one needs to slicing which makes the space
complexity no longer O(1). One can also manually make a loop and do the
reversal but that is even slower than slicing. List.reverse() does not t

This is a little off-topic, but I'm curious, since usually, for public
functions and classes, I do

I certainly will not claim to be the arbitrator of good and bad practices

The space complexity of a list is not constant

If this is something you actually need, write a subclass of list in Cython

I see. I do agree that my reply brings about that 'verbose repeated' feeling,
haha. But for the record, it's not about having something in hand now for the
future, but it's more of a paradigmatic approach to the implementation. Python
has changed for the better in terms of necessity:

12 matches
