It seems to me they are currently /underrated/ in the Python community. Or,
I suspect, everybody disrespects them in public but secretly use them when
they're hacking ;-)

Oh yes, agreed there.  str.split, str.startswith, substr in str ... take you
a long way without a single backslash. I use them more frequently these
days; for example, I would have solved the original poster's problem in that
way.

However, there is a set of common problems which would be hell to solve
without regexes. I used to do that stuff in C when I was young and stupid;
now would never go back to hand-coded, buggy loops just for the sake of
avoiding regexes.

Possibly I have more need of regexes than some others, because I do a lot of
traditional Unix programming, which is heavy on text processing and
text-based mini-languages.
