Paylines: The lines on which symbols must align to win.
Betting: The amount of money a player wagers on a spin.
Payouts: The winnings a player receives based on the symbols aligned.

Building the Slot Machine

Step 1: Setting Up the Environment

First, create a new Python file, e.g., slot_machine.py. This will be the main file where you’ll write your code.

Step 2: Defining the Slot Machine Class

Create a class to represent the slot machine. This class will contain methods to handle the game logic, such as spinning the reels and calculating payouts.

import random

class SlotMachine:
    def __init__(self):
        self.symbols = ['🍒', '🍋', '🍇', '🔔', '⭐', '💎']
        self.reels = 3
        self.paylines = 1
        self.bet = 1
        self.balance = 100

    def spin(self):
        return [random.choice(self.symbols) for _ in range(self.reels)]

    def calculate_payout(self, result):
        if len(set(result)) == 1:
            return self.bet * 10
        elif len(set(result)) == 2:
            return self.bet * 2
        else:
            return 0

Step 3: Implementing the Spin Function

The spin method randomly selects symbols for each reel. The calculate_payout method determines the winnings based on the symbols aligned.

Step 4: Handling User Input and Game Logic

Create a loop to handle user input and manage the game flow. The player can choose to spin the reels or quit the game.

def play_game():
    slot_machine = SlotMachine()
    while slot_machine.balance > 0:
        print(f"Balance: {slot_machine.balance}")
        action = input("Press 's' to spin, 'q' to quit: ").lower()
        if action == 'q':
            break
        elif action == 's':
            result = slot_machine.spin()
            payout = slot_machine.calculate_payout(result)
            slot_machine.balance -= slot_machine.bet
            slot_machine.balance += payout
            print(f"Result: {' '.join(result)}")
            print(f"Payout: {payout}")
        else:
            print("Invalid input. Please try again.")
    print("Game over. Thanks for playing!")

if __name__ == "__main__":
    play_game()
