For regexps I sometimes do it with a specially created class instance.
Something like:
save = Cache_match()
if save.find(a, "3"):
print "it's here:", save.result
else:
print "no 3's here"
Implementing Cache_match is left to you as an exercise. It does make
your code a bit cleaner if you're doing lots of matching.
