Blackjack is a popular card game that has been played for centuries. The game involves a player trying to beat the dealer by getting a hand that is worth more than the dealer’s hand without going over 21.
It’s a simple yet exciting game that has made its way into the digital world. In this tutorial, we will explore whether it is possible to make Blackjack in Python and how you can go about doing it.

What is Python?
Python is an interpreted, high-level, general-purpose programming language that was created in the late 1980s. It has since become one of the most popular programming languages due to its simplicity, readability, and versatility. Python can be used for web development, data analysis, artificial intelligence, machine learning, and much more.
Can You Make Blackjack in Python?
Yes, you can make Blackjack in Python! In fact, there are many tutorials and resources available online that can help you get started with creating your own version of the game. The process involves using various programming concepts such as object-oriented programming (OOP), functions, and loops.
Steps to Make Blackjack in Python
Here are the steps you can follow to create your own version of Blackjack in Python:
- Create a deck of cards
- Shuffle the deck
- Create a player class
- Create a dealer class
- Create a game class
- Implement the game logic
Creating a Deck of Cards
The first step in creating your own version of Blackjack in Python is to create a deck of cards. You can do this by using lists or dictionaries to represent each card. Here’s an example:
suits = ['Hearts', 'Diamonds', 'Clubs', 'Spades']
values = ['Ace', '2', '3', '4', '5', '6', '7', '8', '9','10','Jack','Queen','King']
class Card:
def __init__(self, suit, value):
self.suit = suit
self.value = value
def __repr__(self):
return f"{self.value} of {self.suit}"
class Deck:
def __init__(self):
self.cards = [Card(suit, value) for suit in suits for value in values]
def shuffle(self):
if len(self.cards) > 1:
random.shuffle(self.cards)
def deal_card(self):
if len(self.cards) > 1:
return self.cards.pop(0)
This code creates a deck of cards using two lists to represent the suits and values. It then defines two classes – `Card` and `Deck`. The `Card` class represents a single card and has two attributes – `suit` and `value`. The `Deck` class represents a deck of cards and has three methods – `__init__`, `shuffle`, and `deal_card`.
The `__init__` method creates the deck by looping through the lists of suits and values and creating a new card for each combination. The `shuffle` method shuffles the deck using Python’s built-in random module. Finally, the `deal_card` method deals a card from the top of the deck by removing it from the list of cards.
Creating Player and Dealer Classes
The next step is to create classes for the player and dealer. Here’s an example:
class Player:
def __init__(self, name):
self.name = name
self.hand = []
def add_card(self, card):
self.hand.append(card)
def get_value(self):
value = 0
for card in self.hand:
if card.value == 'Ace':
if value + 11 > 21:
value += 1
else:
value += 11
elif card.value in ['King', 'Queen', 'Jack']:
value += 10
else:
value += int(card.value)
return value
class Dealer:
def __init__(self):
self.name = "Dealer"
self.hand = []
These classes represent the player and dealer and have two methods each – `__init__` and `add_card`. The `__init__` method initializes the name and hand attributes.
The `add_card` method adds a new card to the player’s or dealer’s hand. Additionally, both classes have a `get_value` method that calculates the total value of the cards in the hand using the rules of Blackjack.
Creating a Game Class
The next step is to create a game class that will control the flow of the game. Here’s an example:
class Game:
def __init__(self):
self.deck = Deck()
self.deck.shuffle()
self.player = Player("Player")
self.dealer = Dealer()
def deal_cards(self):
for i in range(2):
self.player.add_card(self.deal_card())
self.dealer.deal_card())
def player_turn(self):
while True:
print(f"\n{self.name}'s turn")
print(f"Hand: {[str(card) for card in self.hand]}")
print(f"Value: {self.get_value()}")
if self.get_value() > 21:
print("Bust!")
return
choice = input("Do you want to hit or stand? ").lower()
if choice == "hit":
self.deal_card())
elif choice == "stand":
return
else:
print("Invalid choice, please try again.")
def dealer_turn(self):
while True:
print(f"\n{self.get_value() > 21:
print("Dealer busts, you win!")
return
if self.get_value() >= 17:
return
self.deal_card())
def determine_winner(self):
player_value = self.get_value()
dealer_value = self.get_value()
if player_value > 21:
print("You bust, dealer wins!") elif dealer_value > 21:
print("Dealer busts, you win!")
elif player_value > dealer_value:
print("You win!") elif dealer_value > player_value:
print("Dealer wins!") else:
print("It's a tie!")
This class represents the game and has four methods - `__init__`, `deal_cards`, `player_turn`, `dealer_turn`, and `determine_winner`. The `__init__` method initializes the deck, player, and dealer. The `deal_cards` method deals two cards to both the player and dealer.
The `player_turn` method allows the player to take their turn by choosing to hit or stand until they either bust or choose to stand. The `dealer_turn` method allows the dealer to take their turn by hitting until they have a value of 17 or higher. Finally, the `determine_winner` method compares the values of the player's and dealer's hands to determine who wins.
Implementing the Game Logic
The final step is to put all of these classes together and implement the game logic. Here's an example:
def play_game():
game = Game()
game.deal_cards()
print(f"Dealer shows: {game.hand[0]}")
print(f"Your hand: {[str(card) for card in game.hand]}")
game.player_turn()
game.dealer_turn()
game.determine_winner()
play_game()
This code calls the `play_game` function that creates a new instance of the Game class, deals two cards to both players, displays one of the dealer's cards, and allows the player and dealer to take their turns before determining who wins.
Conclusion
In conclusion, making Blackjack in Python is definitely possible. By using various programming concepts such as object-oriented programming (OOP), functions, and loops, you can create your own version of this popular card game. With this tutorial as your guide, you can start building your own Blackjack game in Python today!
