I would like Python's any/all better if they took predicates.

anyall.py

from functools import reduce

nopred = lambda i: i
def any(it, pred=nopred):
  '''True if pred(i) is True for any member of the iterable `it`.
  If pred is None, pred(i) == i.
  Like the builtin `any`, return False if `it` is empty.'''
  if not callable(pred):
    pred = nopred
  def accumulate(prev, cur):
    return prev or pred(cur)
  return reduce(accumulate, it, False)

def all(it, pred=nopred):
  '''True if pred(i) is True for all members of the iterable `it`.
  If pred is None, pred(i) == i.
  Like the builtin `all`, return True if `it` is empty.'''
  if not callable(pred):
    pred = nopred
  def accumulate(prev, cur):
    return prev and pred(cur)
  return reduce(accumulate, it, True)
