3. Coding a Single Game of Rock Paper Scissors in Python
Let’s start by coding a single round of rock paper scissors. This involves taking user input, having the computer choose an action, and determining the winner.
3.1. Importing the random Module
To begin, import the random module. This module will help the computer make random choices:
import randomThe random module provides functions for generating random numbers, which we’ll use to simulate the computer’s choices. This ensures the game is unpredictable and fair.
3.2. Taking User Input with input()
Next, take input from the user using the input() function:
user_action = input("Enter a choice (rock, paper, scissors): ")This line prompts the user to enter their choice and stores it in the user_action variable. The user can type “rock”, “paper”, or “scissors”.
3.3. Making the Computer Choose
To make the computer choose its action, use the random.choice() function:
possible_actions = ["rock", "paper", "scissors"]
computer_action = random.choice(possible_actions)
print(f"nYou chose {user_action}, computer chose {computer_action}.n")This code defines a list of possible actions and then randomly selects one for the computer. The random.choice() function ensures each action has an equal chance of being chosen.
3.4. Determining a Winner
Now, determine the winner by comparing the user’s choice with the computer’s choice:
if user_action == computer_action:
print(f"Both players selected {user_action}. It's a tie!")
elif user_action == "rock":
if computer_action == "scissors":
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == "paper":
if computer_action == "rock":
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == "scissors":
if computer_action == "paper":
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")This block of code checks for all possible outcomes and prints the appropriate message. It first checks for a tie and then determines the winner based on the rules of rock paper scissors.
3.5. Complete Code for a Single Game
Here is the complete code for a single game:
import random
user_action = input("Enter a choice (rock, paper, scissors): ")
possible_actions = ["rock", "paper", "scissors"]
computer_action = random.choice(possible_actions)
print(f"nYou chose {user_action}, computer chose {computer_action}.n")
if user_action == computer_action:
print(f"Both players selected {user_action}. It's a tie!")
elif user_action == "rock":
if computer_action == "scissors":
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == "paper":
if computer_action == "rock":
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == "scissors":
if computer_action == "paper":
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")This code allows you to play one round of rock paper scissors. However, to make the game more engaging, you’ll want to allow players to play multiple rounds.
4. Playing Several Games in a Row Using Loops
To allow the game to be played multiple times, you can use a while loop. This loop will continue to run until the user decides to quit.
4.1. Implementing a while Loop
Wrap the game logic inside a while True loop:
import random
while True:
user_action = input("Enter a choice (rock, paper, scissors): ")
possible_actions = ["rock", "paper", "scissors"]
computer_action = random.choice(possible_actions)
print(f"nYou chose {user_action}, computer chose {computer_action}.n")
if user_action == computer_action:
print(f"Both players selected {user_action}. It's a tie!")
elif user_action == "rock":
if computer_action == "scissors":
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == "paper":
if computer_action == "rock":
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == "scissors":
if computer_action == "paper":
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThe while True loop makes the game run indefinitely until the user chooses to stop. The break statement exits the loop when the user enters anything other than “y”.
4.2. Adding a Play Again Option
To allow the user to play again, add an input prompt at the end of the loop:
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis code asks the user if they want to play again. If the user enters anything other than “y” (case-insensitive), the loop breaks and the game ends.
4.3. Handling User Input Errors
To make the game more robust, handle potential input errors. For example, the user might enter an invalid choice. Add a check to ensure the user’s input is valid:
while True:
user_action = input("Enter a choice (rock, paper, scissors): ").lower()
possible_actions = ["rock", "paper", "scissors"]
if user_action not in possible_actions:
print("Invalid input. Please enter rock, paper, or scissors.")
continue
computer_action = random.choice(possible_actions)
print(f"nYou chose {user_action}, computer chose {computer_action}.n")
if user_action == computer_action:
print(f"Both players selected {user_action}. It's a tie!")
elif user_action == "rock":
if computer_action == "scissors":
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == "paper":
if computer_action == "rock":
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == "scissors":
if computer_action == "paper":
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis updated code converts the user’s input to lowercase and checks if it is in the list of possible actions. If not, it prints an error message and continues to the next iteration of the loop.
5. Cleaning Up Your Code with enum.IntEnum
To improve the readability and maintainability of your code, you can use enum.IntEnum. This allows you to define a set of named integer constants.
5.1. Importing IntEnum
First, import IntEnum from the enum module:
from enum import IntEnumThis imports the IntEnum class, which you’ll use to define your actions.
5.2. Defining Actions with IntEnum
Define an Action class using IntEnum:
class Action(IntEnum):
Rock = 0
Paper = 1
Scissors = 2This creates an Action class with three possible values: Rock, Paper, and Scissors. Each value is assigned an integer constant.
5.3. Using IntEnum in Your Code
Update your code to use the Action enum:
import random
from enum import IntEnum
class Action(IntEnum):
Rock = 0
Paper = 1
Scissors = 2
while True:
try:
user_action = int(input("Enter a choice (rock[0], paper[1], scissors[2]): "))
user_action = Action(user_action)
except ValueError:
print("Invalid input. Please enter 0, 1, or 2.")
continue
computer_action = random.choice(list(Action))
print(f"nYou chose {user_action.name}, computer chose {computer_action.name}.n")
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif user_action == Action.Rock:
if computer_action == Action.Scissors:
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == Action.Paper:
if computer_action == Action.Rock:
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == Action.Scissors:
if computer_action == Action.Paper:
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis updated code uses the Action enum to represent the possible actions. The user now enters a number corresponding to their choice.
6. Structuring Your Code with Functions
To further organize your code, you can split it into functions. Each function will handle a specific task, such as getting user input, making the computer choose, and determining the winner.
6.1. Defining Functions
Define functions for each part of the game:
import random
from enum import IntEnum
class Action(IntEnum):
Rock = 0
Paper = 1
Scissors = 2
def get_user_selection():
while True:
try:
user_action = int(input("Enter a choice (rock[0], paper[1], scissors[2]): "))
return Action(user_action)
except ValueError:
print("Invalid input. Please enter 0, 1, or 2.")
def get_computer_selection():
return random.choice(list(Action))
def determine_winner(user_action, computer_action):
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif user_action == Action.Rock:
if computer_action == Action.Scissors:
print("Rock smashes scissors! You win!")
else:
print("Paper covers rock! You lose.")
elif user_action == Action.Paper:
if computer_action == Action.Rock:
print("Paper covers rock! You win!")
else:
print("Scissors cuts paper! You lose.")
elif user_action == Action.Scissors:
if computer_action == Action.Paper:
print("Scissors cuts paper! You win!")
else:
print("Rock smashes scissors! You lose.")
while True:
user_action = get_user_selection()
computer_action = get_computer_selection()
print(f"nYou chose {user_action.name}, computer chose {computer_action.name}.n")
determine_winner(user_action, computer_action)
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis code defines three functions: get_user_selection(), get_computer_selection(), and determine_winner(). Each function handles a specific part of the game logic.
6.2. Calling Functions in the Main Loop
Call the functions in the main loop to play the game:
while True:
user_action = get_user_selection()
computer_action = get_computer_selection()
print(f"nYou chose {user_action.name}, computer chose {computer_action.name}.n")
determine_winner(user_action, computer_action)
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis loop calls the functions to get the user’s choice, the computer’s choice, and determine the winner. This makes the code more readable and easier to maintain.
7. Adding More Complex Rules with Dictionaries
To make the game more interesting, you can add more complex rules. For example, you can add Lizard and Spock as possible actions. To handle these complex rules, you can use dictionaries.
7.1. Defining a victories Dictionary
Define a victories dictionary that specifies which actions each action beats:
import random
from enum import IntEnum
class Action(IntEnum):
Rock = 0
Paper = 1
Scissors = 2
Lizard = 3
Spock = 4
victories = {
Action.Scissors: [Action.Lizard, Action.Paper],
Action.Paper: [Action.Spock, Action.Rock],
Action.Rock: [Action.Lizard, Action.Scissors],
Action.Lizard: [Action.Spock, Action.Paper],
Action.Spock: [Action.Scissors, Action.Rock]
}
def get_user_selection():
while True:
try:
user_action = int(input("Enter a choice (rock[0], paper[1], scissors[2], lizard[3], spock[4]): "))
return Action(user_action)
except ValueError:
print("Invalid input. Please enter 0, 1, 2, 3, or 4.")
def get_computer_selection():
return random.choice(list(Action))
def determine_winner(user_action, computer_action):
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif computer_action in victories[user_action]:
print(f"{user_action.name} beats {computer_action.name}! You win!")
else:
print(f"{computer_action.name} beats {user_action.name}! You lose.")
while True:
user_action = get_user_selection()
computer_action = get_computer_selection()
print(f"nYou chose {user_action.name}, computer chose {computer_action.name}.n")
determine_winner(user_action, computer_action)
play_again = input("Play again? (y/n): ")
if play_again.lower() != "y":
breakThis code adds Lizard and Spock to the Action enum and defines the victories dictionary. The victories dictionary specifies which actions each action beats.
7.2. Updating the determine_winner Function
Update the determine_winner function to use the victories dictionary:
def determine_winner(user_action, computer_action):
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif computer_action in victories[user_action]:
print(f"{user_action.name} beats {computer_action.name}! You win!")
else:
print(f"{computer_action.name} beats {user_action.name}! You lose.")This updated function checks if the computer’s action is in the list of actions that the user’s action beats. If it is, the user wins. Otherwise, the computer wins.
8. Enhancing the User Interface
To make the game more user-friendly, you can enhance the user interface. This includes providing clear instructions, displaying the choices, and showing the results in a more appealing way.
8.1. Displaying Choices
Display the available choices to the user:
def get_user_selection():
while True:
try:
choices = [f"{action.name}[{action.value}]" for action in Action]
choices_str = ", ".join(choices)
user_action = int(input(f"Enter a choice ({choices_str}): "))
return Action(user_action)
except ValueError:
print("Invalid input. Please enter a valid number.")This updated function displays the available choices to the user, making it easier for them to make a selection.
8.2. Adding Visual Elements
You can add visual elements to the game, such as ASCII art or emojis, to make it more engaging. For example:
rock_art = """
_______
---' ____)
(_____)
(_____)
(____)
---.__(___)
"""
paper_art = """
_______
---' ____)____
______)
_______)
_______)
---.__________)
"""
scissors_art = """
_______
---' ____)____
______)
__________)
(____)
---.__(___)
"""
lizard_art = """
_______
---' ____)____
______)
__________)
(____)
---.__(___)
"""
spock_art = """
_______
---' ____)____
______)
__________)
(____)
---.__(___)
"""
action_art = {
Action.Rock: rock_art,
Action.Paper: paper_art,
Action.Scissors: scissors_art,
Action.Lizard: lizard_art,
Action.Spock: spock_art
}
def determine_winner(user_action, computer_action):
print(f"nYou chose:n{action_art[user_action]}")
print(f"Computer chose:n{action_art[computer_action]}")
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif computer_action in victories[user_action]:
print(f"{user_action.name} beats {computer_action.name}! You win!")
else:
print(f"{computer_action.name} beats {user_action.name}! You lose.")This code adds ASCII art for each action and displays it when the user and computer make their choices.
8.3. Improving the Output
Improve the output by adding colors and formatting to make it more visually appealing. You can use libraries like colorama to add colors to the output:
import colorama
from colorama import Fore, Style
colorama.init()
def determine_winner(user_action, computer_action):
print(f"nYou chose:n{Fore.GREEN}{action_art[user_action]}{Style.RESET_ALL}")
print(f"Computer chose:n{Fore.RED}{action_art[computer_action]}{Style.RESET_ALL}")
if user_action == computer_action:
print(f"Both players selected {user_action.name}. It's a tie!")
elif computer_action in victories[user_action]:
print(f"{Fore.GREEN}{user_action.name} beats {computer_action.name}! You win!{Style.RESET_ALL}")
else:
print(f"{Fore.RED}{computer_action.name} beats {user_action.name}! You lose.{Style.RESET_ALL}")This code uses the colorama library to add colors to the output, making it more visually appealing.
9. Adding Error Handling and Validation
To make your game more robust, it’s essential to add error handling and validation. This ensures that the game behaves correctly even when the user enters invalid input.
9.1. Handling Invalid Input
Handle invalid input by using try and except blocks:
def get_user_selection():
while True:
try:
choices = [f"{action.name}[{action.value}]" for action in Action]
choices_str = ", ".join(choices)
user_action = int(input(f"Enter a choice ({choices_str}): "))
return Action(user_action)
except ValueError:
print("Invalid input. Please enter a valid number.")This code handles the ValueError exception that is raised when the user enters a non-integer value.
9.2. Validating User Input
Validate user input to ensure it is within the valid range of choices:
def get_user_selection():
while True:
try:
choices = [f"{action.name}[{action.value}]" for action in Action]
choices_str = ", ".join(choices)
user_action = int(input(f"Enter a choice ({choices_str}): "))
if Action(user_action) not in Action:
raise ValueError
return Action(user_action)
except ValueError:
print("Invalid input. Please enter a valid number.")This code raises a ValueError if the user enters a number that is not a valid action.
