Before I go reinventing the wheel, can anyone tell me if there's a drop-in (or semi-drop-in) replacement for the single-line statement:

allfiles = dircache.listdir('.')

One line? No. But you can just do:

global_cache = {}
def cached_listdir(path):res = global_cache.get(path)if res is None:res = os.listdir(path)global_cache[path] = resreturn res
