Python - Create And Instantiate Class

I am building a class of playlists, which will hold many playlists of the same genre. class playlist(object): def __init__(self,name): self.name = name I would like

Solution 1:

If I understand correctly, you want playlists and users

class Playlist(object):
    def __init__(self, name):
        self.name = name
        self.liked_by = list()

    @classmethod
    def get_genre(cls, genre):
        # this relies on no instance of this class
        pass
        # return api data...

class User(object):
     def __init__(self, name):
         self.name = name

     def likes_playlist(self, playlist):
         playlist.liked_by.append(self.name)

And then, some examples

playlists = list()
hard_rock = Playlist('hard_rock')

joe = User('joe')
joe.likes_playlist(hard_rock)

playlists.append(hard_rock)
playlists.append(Playlist('pop_rock'))

country = Playlist.get_genre('country')

Solution 2:

Something like this would be possible if playlists are the core component of your application (very simple example using class inheritance).

>>> class playlist:
...     def __init__(self,name, user):
...         self.name = name
...         self.user = user
... 
>>> class hardrock(playlist):
...     def __init__(self,name, user):
...         playlist.__init__(self, name, user)
... 
>>> test = hardrock('my_awesome_hardrock_list', 'my_awesome_username')
>>> print test.name
my_awesome_hardrock_list
>>> print test.user
my_awesome_username

You could start using just strings for users and later replace them with real objects and add some kind of relations between playlists and users. See cricket_007's suggestion for some more ideas.
