Here is a yet more simple version, I wonder if it still does the same
thing, whatever it is you are looking for :-)
def xsplitter(iseq, pred):
class It(object):
def __init__(self, fun, parity):
self.divert = fun
self.parity = parity
self.queue = collections.deque()
def append(self, item):
self.queue.append(item)
def __iter__(self):
while self.queue:
yield self.queue.popleft()
for item in iseq:
if pred(item) == self.parity:
yield item
else:
self.divert(item)
for x in self:
yield x
it1 = It(lambda y: it2.append(y), True)
it2 = It(lambda y: it1.append(y), False)
return it1, it2
A.
