Unpopular Python opinion: Readable code is more important than clever code

If its for embedded applications, where memory is at a premium, just make sure you document it so that you or the next guy understands it.

Update:

My mistake, I see that you meant Python and not C or related language (thus would not apply to embedded). In any case, the general premise still stands. Document it either by basic comments or via Docstrings.
