💻 Activity 9.3: Building the game LCR#

Left-Center-Right (also known as LCR) is a simple dice game that can be played with any number of players, making it a great option for parties or family gatherings. The game requires three six-sided dice and a handful of chips or other small items to use as currency. Here are the rules:

Each player starts with three chips.
The game begins with each player rolling the three dice.
The result of the roll determines what action each player must take:
- If a player rolls an “L,” they must pass one chip to the player on their left.
- If a player rolls an “R,” they must pass one chip to the player on their right.
- If a player rolls a “C,” they must put one chip into the center pot.
- If a player rolls a number, they keep their chips for that round.
The game continues with each player rolling the dice and following the corresponding action until only one player has any chips left.
The player with chips remaining is the winner and collects all the chips from the center pot.
If a player runs out of chips, they are out of the game.
If a player has only one chip left, they only roll one dice.
Players can agree to increase the number of chips each player starts with or add other variations to the game to make it more interesting.

That’s it! LCR is a quick and easy game to learn, but it can be surprisingly addictive and competitive.

You will build this game using classes an inheritance. Again, we will be practicing your ability to problem solve in code.

import random


# Import the random module.
# Define a new class called Dice.
# Within the Dice class, define an __init__ method that initializes the class with a list of sides. 
# By default, the list contains the strings "L", "R", and "C".
# Within the Dice class, define a roll method that returns a random element from the list of sides.
# To create a new Dice object, create a new instance of the class.
# To roll the die, call the roll method on your Dice object.
# If you want to create a Dice object with custom sides, pass a list of strings representing the sides when you create the object.
...


# Define a new class called Player.
# The Player class should inherit from the Dice class.
# Within the Player class, define an __init__ method that initializes the class with a name, position, chips, CPU, and dice value. 
# chips should be set to 3 by default, and CPU should be set to True by default. 
# If a dice object is passed, the sides of the Player object's dice should be set to the sides of the passed dice object.
# Within the Player class, define a take_chip method that subtracts one chip from the player's chips value and returns 1.
# Within the Player class, define a give_chip method that adds one chip to the player's chips value and returns 1.
class Player(...):
    def __init__(...):
        super().__init__()
        if dice is not None:
            self.sides = dice.sides
        ...

    def take_chip(self):
        ...

    def give_chip(self):
        ...


# Define a list of players instantiated from the `Player` class above
# Make it so the 0th player is a human and a cheater by having biased dice
players = ...


# initialize center_pot as 0
...


# Create a while loop that runs as long as the length of the players list is greater than 1.
# Within the while loop, use a for loop to iterate through each player in the players list.
# Print out the current state of the game, including the number of chips each player has and the number of chips in the center pot.
# Wait for the user to press the Enter key to continue.
# Roll the dice for the current player a number of times equal to the player's current number of chips.
# Print out the result of each roll.
# For each roll:
# If the roll is an "L," the current player should take a chip and give it to the player to their left. Print a message indicating the chip transfer.
# If the roll is an "R," the current player should take a chip and give it to the player to their right. Print a message indicating the chip transfer.
# If the roll is a "C," the current player should put a chip in the center pot. Print a message indicating the chip transfer.
# If the roll is a number, do nothing.
# If the current player has no chips remaining, remove them from the players list. You can use the list method `.remove`
# Update each player's position attribute to reflect their new position in the players list, and who they pass to. 
# This helps correct if someone was removed from the game.
# hint, the player to the right can be determined using `players[(player.position + 1) % len(players)]`
