Or even:
def equal_items(iter1, iter2, key=lambda x: x):
iter1, iter2 = iter(iter1), iter(iter2)
for x, y in izip(iter1, iter2):
if key(x) != key(y):
return False
return not any(izip_longest(iter1, iter2))
(untested)
Or even:
def equal_items(iter1, iter2, key=lambda x: x):
iter1, iter2 = iter(iter1), iter(iter2)
if any(key(x) != key(y) for x, y in izip(iter1, iter2)):
return False
return not any(izip_longest(iter1, iter2))
