can anyone tell me why I'm getting this error ?

In addition to an _init__method we'll want to add methods to shuffle our deck, and to deal out cards during gameplay OPTIONAL: We may never need to print the contents of the deck during gameplay, but having the ability to see the cards inside it may help troubleshoot any problems that occur during development. With this in mind, consider adding a _str_ method to the class definition [49]: class Deck: def definit__(self): self.deck - [] # start with an empty list for suit in suits: for rank in ranks: self.deck.append(Card(suit, rank)) # build Card objects and add str_(self): deck_comp # start with an empty string for card in self.deck: deck_comp + ' '+card._str_() # add each Card object's print str return 'The deck has:' + deck_comp def shuffle(self): random.shuffle(self.deck) def deal(self): single_card self.deck.pop() return single_card TESTING: Just to see that everything works so far, let's see what our Deck looks like!

You might add an attribute for "value" - We chose to handle value later when developing our Hand class. In addition to the Card's _init_method, consider adding a __str__method that, when asked to print a Card, returns a string in the form "Two of Hearts" [48]: def init__(self, suit, rank) self.suit - suit self.rank - rank def__str_(self): return self.rank. of self.suit Step 3: Create a Deck Class Here we might store 52 card objects in a list that can later be shuffled First, though, we need to instantiate all 52 unique card objects and add them to our list. So long as the card class definition appears in our code, we can build Card objects inside our Deck_init_method Consider iterating over sequences of suits and ranks to build out each card. This might appear inside a Deck class method for suit in suits: for rank in ranks: In addition to an __init_method we'll want to add methods to shuffle our deck, and to deal out cards during gameplay OPTIONAL We may never need to print the contents of the deck during gameplay, but having the ability to see the cards inside it may help troubleshoot any problems that occur during development within mind, consider adding a Str method to the class definition in (aoy: class beck: T2 29/01/2027
