If you're interested then it isn't all that hard to open up re.py in an editor and see that the cache holds up to 100 items. Of course that's just an implementation detail so other versions might have a different size cache. Also implementation dependant, but it might be worth knowing that when you hit that limit the cache is simply cleared: there's no gradual clearing of the oldest or least used entries. -- http://mail.python.org/mailman/listinfo/python-list
