Simple Python Game: Rock, Paper, Scissors

In this post, we will write a simple Python program to implement the Rock, Paper, Scissors game with a detailed explanation.

Rules for Rock, Paper, Scissors game

• Rock is won over scissors
• Scissor is won over Paper
• Paper is won over Rock

Algorithms for Rock, Paper, Scissors

Step-1:import random module.

Step-2: create a list [stone,paper,scissor]

Step-3: take user input 0 --> stone, 1 --> paper, 2 --> scissor (user choice).

Step-3: using random.randint(0,2) generate random number from 0 to 2 (this is a computer choice).

Step-4: print user_choice and computer_choice.

Step-5: if user_choice == 0 and computer_choice == 2 then user will win (0 stand for stone and 2 stand for scissors).

Step-6: elif user_choice == 2 and computer_choice == 0 then computer will win (opposite of step-5).

Step-7: elif computer_choice>user_choice then computer win because now only two options are left 0 or 1 (0 for stone or 1 for paper). if computer_choice>user_choice means computer choice is 1 which is equal to paper and user choice is 0 which is equal to stone (paper won over a stone).

Step-8: elif user_choice>computer_choice then user wins (opposite of step-7).

Step-9: otherwise the game is a draw.

this is a very exciting python mini project for beginners. So let’s open your IDEs and start writing code for the stone, paper, scissors game.

Bur before writing a program you should know about:

1. random module
2. python list
3. if-elif-else
4. python operators.

Source code

import random

stone = '''
---'   ____)
      (_____)
      (_____)
      (____)
---.__(___)
'''

paper = '''
    _______
---'   ____)____
          ______)
          _______)
         _______)
---.__________)
'''

sizzer = '''
---'   ____)____
          ______)
       __________)
      (____)
---.__(___)
'''

image_choice = [stone,paper,sizzer] 

print('stone paper sizerer game choose 0-stone, 1-paper, 2-sizzer')

user_choice = int(input('Enter your choise : '))  #user choice 
print('Your choice:\n')
print(image_choice[user_choice])  

computer_choice = random.randint(0,2)  #computer choice

print('Computer choice:\n')
print(image_choice[computer_choice])

if user_choice >2 or user_choice<0:
    print('You lose !! (Because choice wrong input )')
elif user_choice == 0 and computer_choice == 2:
    print('you win !!')
elif computer_choice == 0 and user_choice == 2:
    print('You Lose !!')
elif computer_choice>user_choice:
    print('you Lose !')
elif user_choice>computer_choice:
    print('you win !!')
elif user_choice == computer_choice:
    print('It\'s Draw !!!')

Output

stone paper sizerer game choose 0-stone, 1-paper, 2-sizzer
Enter your choise : 2
Your choice:


---'   ____)____
          ______)
       __________)
      (____)
---.__(___)

Computer choice:


    _______
---'   ____)____
          ______)
          _______)
         _______)
---.__________)

you win !!
