class A(object):
x = 0
def set_x(cls, val):
cls.x = val
set_x = classmethod(set_x)
>>> a = A()
>>> print a.x
0
>>> A.set_x(37)
>>> print a.x
37
I think that classmethod only works with new-style classes, and only in
recent versions of python. see the docs for more information. see also
"staticmethod".
