I second this. And it also has great documentation, both off and online.
See for example: http://docs.python.org/2/howto/regex.html and
http://docs.python.org/2/library/re.html (and note that I am one of the few
people who think Python documentation in general should be improved,
because is not as good as e.g. java's).

One *extremely* useful feature of Python's regex is re.VERBOSE (see
http://docs.python.org/2/howto/regex.html#using-re-verbose for details).
While writing it might not seem a big deal, but when reading a regex you
wrote the day before (not to mention the month or year before) it's
priceless. I refuse to write something (besides the absolutely trivial)
without using re.VERBOSE.
