Agreed, regex is the last tool I reach for in python code.
I find I use split() a lot to break up strings for processing.
But there are cases where a regex is the best tool for a particular job
and I then use the re module. But it costs in maintainability.
I speak as the author of a regex engine and know how to write scary
regex's when the need arises.
