I would envision something along the lines of:

class Game:

class Player:

    def __init__(self, name):
        self._name = name
        self._hand = Hand()
    def deal(self, card):

class Card: pass

class Hand: pass

class Deck: pass

Your game is encapsulated by the Game class, which owns a list of 
players. This uses all of the bits of advice that Ken and Sean gave out. 
It also adds some more pieces to the puzzle, adding in all of the object 
you're likely to find at a casino blackjack table (save the chips and
