Python - multiple inheritance with same name

Question

I have main class as:

class OptionsMenu(object):

    def __init__(self, name):
        try:
            self.menu = getattr(self, name)()
        except:
            self.menu = None

    @staticmethod
    def cap():
        return ['a', 'b']

and have a child class override as:

class OptionsMenu(OptionsMenu):
    @staticmethod
    def cap():
        return ['a', 'b', 'c']

The first class gives the menu options for default template, while next gives for some other template.

I want another class OptionsMenu derived from child class, and get the list (['a', 'b', 'c']) and make changes to that.

Is this achievable in python? If yes, how may I achieve this?

Many thanks for any help!

It is possible if the two `OptionsMenu` are in distinct modules, but... why that? — Maxime Lorant, Mar 26 '16 at 18:20
You derived a second class, what's preventing you from deriving a third one? — Stop harming Monica, Mar 26 '16 at 18:42

Nothing stops you from getting result of parent's static function:

class OptionsMenu:
    @staticmethod
    def cap():
        return ['a', 'b', 'c']


class OptionsMenu(OptionsMenu):
    @staticmethod
    def cap():
        lst = super(OptionsMenu, OptionsMenu).cap()  # ['a', 'b', 'c']
        lst.append('d')
        return lst

print(OptionsMenu.cap())  # ['a', 'b', 'c', 'd']

But as noted to give same class names for different classes is very bad idea! It will lead to many problems in future.

Try to think, why do you want same names for different classes. May be they should have different names?

class OptionsMenu

class SpecialOptionsMenu(OptionsMenu)

Or may be as soon as cap() is static method, make different functions out of OptionsMenu?

def cap1(): return ['a', 'b', 'c']

def cap2(): return cap1() + ['d']
