[docs] [issue24195] Add `Executor.filter` to concurrent.futures

[Brian Quinlan]

Brian Quinlan added the comment:

Actually it immediately converts the iterable into a list. Recall:

def filter(self, fn, iterable, timeout=None):
  l = list(iterable)  # iterable => list
  return (item for (item, keep) in zip(l, self.map(fn, l, timeout)) if keep)
