[Chicago] Assistance on program failing to fully run

[SKHUMBUZO ZIKHALI]

Hi 
 
I am trying to run the following program from Guide to Programming with Python by Micheal Dawson:
 

class Card(object):
    RANK = ["A","2","3","4","5","6","7"
            "8","9","K","Q","J"]
    SUIT = ["s","d","h","c"]
    def __init__(self,rank, suit):
        self.rank = rank
        self.suit = suit
    def __str__(self):
        rep = self.rank + self.suit
        return rep
             
class Hand(object):
    def __init__(self):
        self.cards = []
    def __str__(self):
        if self.cards:
            rep = ''
            for card in self.card:
                rep += str(Card)+''      
        else:
            rep = "<empty>"
            return rep
    def clear(self):
        self.cards =[]
    def add(self, card):
        self.cards.append(card)
    def give(self, card, other_hand):
        self.cards.remove(card)
        other_hand.add(card)
 
# Main
 
card1 = Card(rank = "A", suit ="c")
print 'Printing a Card object'
print card1
card2 = Card(rank = "2", suit ="c")
card3 = Card(rank = "3", suit ="c")
card4 = Card(rank = "4", suit ="c")
card5 = Card(rank = "5", suit ="c")
print card2
print card3
print card4
print card5
my_hand = Hand()
print '\nPrinting my hand before I add my card:'
print my_hand
my_hand.add(card1)
my_hand.add(card2)
my_hand.add(card3)
my_hand.add(card4)
my_hand.add(card5)
print '\nPrinting my hand after adding 5 cards:'
print my_hand
your_hand = Hand()
my_hand.give(card1, your_hand)
my_hand.give(card2, your_hand)
print '\nGave the first two cards from my hand to your hand.'
print 'Your hand:'
print your_hand
print 'My hand:'
my_hand
my_hand.clear()
print '\nMy hand after clearing it:'
raw_input('\n\nPress the enter key to exist.')
 
However, I can partly run it for eventually receive attribute error message. Printing response is as follows: 
 
2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

Printing my hand before I add my card:
<empty>
Printing my hand after adding 5 cards:
Traceback (most recent call last):
  File "C:/Python27/Card Game.py", line 69, in <module>
    print my_hand
  File "C:/Python27/Card Game.py", line 25, in __str__
    for card in self.card:
AttributeError: 'Hand' object has no attribute 'card'
>>> 
 
Would you please help me as to where I got it wrong with this program and lastly inform how how does Hand object gets linked or connected with Card object? 
 
With thanks
