Based on this, I'd say that the best policy would be that if you only have a handful of simple REs that are used only on occasion, it's probably not worth using re.compile--even if they fall out of cache, it shouldn't take a noticeable amount of time to recompile them. If, however, these are either complex REs, or REs that are being used very frequently, say in a loop, might as well save the compiled RE somewhere just to be sure it doesn't have to be recompiled at any point. -- http://mail.python.org/mailman/listinfo/python-list
