Does Python have Class methods

:
:  d = Doubler()
:  d.double(3)
:  # returns 6

The goal is to be able to write:

Doubler.double(3)

not

Doubler().double(3)

Your example yields:

>>> Doubler.double(3)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: unbound method must be called with class instance
>>>

IOW you want a "class method" -- preferably meaning "a method defined for
and invoked on a class object independent of any instance of said class".
