Python: Hur anropar jag en klassmetod?

g = class newgrid:
    def __init__(self, grid, play): #är konstruktor för att injicera ett nytt objekt
        self.grid = grid
        self.play=play

    def play(self): <——
här här här här <—— måste lägga till 
syfte
paramteer
retur värden? som det står i sista länken sida 3.  men jag har ju redan förklarat all syfta osv i defintionen ovan den här kodsnutten i def play_game
g.play()
