    copied!<p>I'm trying to simulate the dealer of a game of blackjack, and I'm really confused.</p> <p>Basically, I'm using a deck of cards that only consists of J, Q, K, A, and 2-10 to simplify this stuff, rather than using an ordinary card deck setup.</p> <p>I realize all of this is pretty messy, I've been working with classes for all of 3 hours.</p> <pre><code>class Deck: '''Simulates a deck of cards.''' def __init__(self): '''Deck() -&gt; Deck Creates a deck of cards''' self.Deck = ['J', 'J', 'J', 'J', 'Q', 'Q', 'Q', 'Q', 'K', 'K', 'K', 'K', 'A', 'A', 'A', 'A', '2', '2', '2', '2', '3', '3', '3', '3', '4', '4', '4', '4', '5', '5', '5', '5', '6', '6', '6', '6', '7', '7', '7', '7', '8', '8', '8', '8', '9', '9', '9', '9', '10', '10', '10', '10'] def __str__(self): '''str(Deck) -&gt; str Returns string showing number of cards left''' output = str(len(self.Deck)) + ' cards' return(output) def shuffle(self): '''shuffle(self) -&gt; Deck Shuffles deck.''' import random random.shuffle(self.Deck) def draw(self): if len(self.Deck) &gt; 0: return(self.Deck.pop(0)) else: return(-1) def add(self, card): self.Deck.append(str(card)) class BlackJackPlayer(Deck): '''Represents someone playing blackjack.''' def __init__(self, Deck): self.BlackJackPlayer = Deck self.hand = '' self.value = 0 def __str__(self): return self.hand def clean_up(self): self.BlackJackPlayer = Deck self.hand = '' self.value = 0 def get_value(self): for x in self.hand: if x != ',': if x not in range(1, 11): if x != 'A': self.value += 10 else: if (self.value + 11) &gt; 17: self.value += 1 else: self.value += 11 else: self.value += x return(self.value) def hit(self): Deck.shuffle(self.BlackJackPlayer) card = Deck.draw(self.BlackJackPlayer) return(card) def play_dealer(self): while BlackJackPlayer.get_value(self) &lt; 17: self.hand += BlackJackPlayer.hit(self) print(self.hand) if BlackJackPlayer.get_value(self) &lt; 17: self.hand += ',' if BlackJackPlayer.get_value(self) &gt; 21: return('BUST') else: return </code></pre> <p>For some reason, whenever I call jack.play_dealer(), it'll stop too early because it thinks the hand is already over 21. </p> <p>For example:</p> <pre><code>&gt;&gt;&gt; deck = Deck() &gt;&gt;&gt; jack = BlackJackPlayer(deck) &gt;&gt;&gt; jack.play_dealer() 7 'BUST' &gt;&gt;&gt; jack.get_value() 40 </code></pre> <p>I'm guessing something's wrong with my get_value(), but I can't figure it out.</p> <p>Thanks in advance!</p>
