New submission from Ram Rachum:
Can't this code:
class Sequence(Sized, Iterable, Container):
# ...
def __contains__(self, value):
for v in self:
if v == value:
return True
return False
Be shortened into this:
class Sequence(Sized, Iterable, Container):
# ...
def __contains__(self, value):
return any(item == value for value in self)
Which can even fit on one line with a lambda:
class Sequence(Sized, Iterable, Container):
# ...
__contains__ = lambda self: any(item == value for value in self)
