Have you actually verified this or are you just guessing? Python
usually doesn't win speed contests with other languages, but that
doesn't mean that it will actually be slower for your particular
If, OTOH, you have actually compared the python solution with solutions
written in other languages then I have to wonder why you aren't using
one of the solutions written in another language. :-)

C would *not* be my choice for anything involving string processing. Ick.
Perl would probably be a good bet if you want to pick a different language.
Perl has a lot of warts, but it is good at string processing and regular
expressions and lots of people know the language so it would be easy to
Before you do that, however, make sure that some other solution actually
would be faster. Don't write a full replacement until you actually have
a simple mostly-functional version that shows the speed benefit.
