I would like create a class in python with method and sub-method.

Example what I want to do :

foo = Foo()
foo.playlist('my playlist').add('i_add_a_track_in_"my playlist".ogg')
foo.playlist('my playlist').delete('i_remove_this_track.ogg')

I have this code for now :

class Foo(object):
    def playlist(self, name):
        pass #my function...
    def add(self, track):
        pass #adding track
    def delete(self, track):
        pass #delete track

Please help me, I don't know how i can do it.

Thank you
