I want to filter strings in a list based on a regular expression.
Is there something better than [x for x in list if r.match(x)] ?

1Actually, list comprehensions are usually prefered over functional constructs such as filter, reduce, lambda, etc.

@Ivo: They are usually preferred because they're usually clearer and often more succinct. However in this case, the `filter` version is perfectly clear and has much less noise.

well, my question was if there's something like random.choice, but for regexps, but the answer seems no :-)
