>>> I assigned a card by this code :
>>> def deal(self, hands, num_cards=999):
>>> num_hands = len(hands)
>>> for i in range(num_cards):
>>> if self.is_empty(): break # break if out of cards
>>> card = self.pop() # take the top card
>>> hand = hands[i % num_hands] # whose turn is next?
>>> hand.add(card) # add the card to the hand
> No this code assigns several HANDS not just cards.
> The code that assigns a card is inside this function, but
> you need to narrow it down to the specific lines assigning the card.
The lines that assign card is :
hand = hands[i % num_hands] # whose turn is next?
hand.add(card) # add the card to the hand
The first one takes care to who a card is assigned and the second one assigned it to that person.

This is not correct. Card is a list and not a directory. See this : self.cards =

oke, but I confused two objects and that is a mistake.

I know that because self.hands is not working.
Now Im busy to make this difficult exercise of writing print_hands()
But thanks for the time and explantion.
OOP is difficult to understand I find.
