Review: Card Dealer

Module 4: IDEs & Tools

Card Dealer

Create a Python function to simulate dealing cards from a deck. The function should perform the following tasks:

1. Generate a full deck of poker cards. Represent each card as a tuple, where the first element is the number or figure (e.g., ÔÇ£KingÔÇØ, ÔÇ£3ÔÇØ), and the second element is the suit (e.g., ÔÇ£HeartsÔÇØ, ÔÇ£SpadesÔÇØ). The deck should include all standard cards (13 cards per suit) and two jokers, resulting in a total of 54 cards. For example, the 10 of Hearts is represented as (10, “Hearts”).
2. Shuffle the deck. The function should randomize the order of the cards in the deck.
3. Deal cards to players. The function should accept two parameters: the list of player names and the number of cards to deal to each player. Distribute the specified number of cards from the shuffled deck to each player.

The output should be a dictionary of lists, like {ÔÇ£DanielÔÇØ: [(ÔÇ£3ÔÇØ, ÔÇ£DiamondsÔÇØ), (ÔÇ£JackÔÇØ, ÔÇ£CloversÔÇØ)]}

Solution

Try the exercise on your own first, then compare with the worked solution below.

# Solution 1

import numpy as np

def create_deck():
  """
  Creates a full deck of poker cards including two jokers.
  Each card is represented as a tuple (value, suit).
  """
  suits = ["Hearts", "Diamonds", "Clubs", "Spades"]
  values = ["2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace"]
  deck = [(value, suit) for suit in suits for value in values]

  # Add two Jokers
  deck.extend([("Joker", "Red"), ("Joker", "Black")])

  return deck

def shuffle_deck(deck):
    """
    Shuffles the given deck of cards.
    """
    np.random.shuffle(deck)
    return deck

def deal_cards(deck, players, cards_per_player):
  """
  Deals a specified number of cards to each player.
  """
  if len(players) * cards_per_player > len(deck):
    raise ValueError("Not enough cards in the deck to deal to all players.")

  hands = {player: [] for player in players}
  for _ in range(cards_per_player):
    for player in players:
      hands[player].append(deck.pop())

  return hands

# Example usage
deck = create_deck()
shuffled_deck = shuffle_deck(deck)
player_hands = deal_cards(shuffled_deck, ["Daniel", "Emma", "Lucas", "Sophia"], 2)  # 4 players, 2 cards each

print(player_hands)

  return ls_deck
