You need to use a 'return' statement:

   def deal_cards(self, num_of_hands, num):
       '''deals x amount of cards(num) to each hand'''
       hands = []
       for i in range(num_of_hands):
           newhand = Hand('hand%d' % i)
           self.deal(newhand, num)
           hands.append(newhand)
           print '::::%s::::' % (handname.label), '\n', handname, '\n'
       return Hand


Then you can write:

>>> hands = deck.deal_cards(4, 5) # On fait une belotte?

And I don't see the need of defining 'Hand' inside 'Deck'.
