So, a good strategy for dealing with this is using classes as singleton objects. This way you can call the classmethods without having to create an instance, but you can create subclasses which overload particular member variables and/or methods.

For example:

class Foo(object):
    foo = 1
    bar = 2
    def blah(cls):
        return +

    duh = True
    def argh(cls):
        if cls.duh:
            return cls.blah()
            return None

class Bar(Foo):
    duh = False

class Duh(Foo):
    bar = 99

Foo.argh() -> 3
Bar.argh() -> None
Duh.arg() -> 100

Hope this helps
