I like this, but it has the same readability issue I noted for cases where decomposition is used:
[(k, v) from somedict.items() if condition(v)]
I don't think that's too bad if you keep in mind that [x from stuff] is a shorthand for [x for x in stuff] whatever x happens to be. So your example would be equivalent to [(k, v) for (k, v) in somedict.items() if condition(v)] As a bonus, the short form could probably be made more efficient, because the tuples produced by the for-loop could be put straight into the result list, instead of having to re-pack k and v into a new tuple. -- Greg
