How will the computer know in advance > that the regex matches only a finite set of possible strings? You don't. Hence, you want something that behaves like a generator, and will produce the strings one at a time. Preferably, for the purposes of useful computation, in some canonical order. I'm sorry to say I don't know of an existing Python module to do this, although you could write one for at least the basic regular expression operators if you wanted. The basic problem isn't all that hard to solve, though the full generality of the re module's input syntax is far more expressive than truly "regular" expressions from language theory.
