Python program to implement Rock Paper Scissors game

Using Python, we can also develop very interesting games. Rock paper scissor game is one of them. Here, we userandint()function to generate random numbers.

In this game, players usually count to three, or say the name of the game, and each time either raise a hand, then swing the fist downward, or hold it down.

Example Code

# importing required random module
import random
print('The Rules of Rock paper scissor game will be follows: 
"
+"Rock vs paper　--> paper wins 
"
+"Rock vs scissor　--> Rock wins 
"
+"paper vs scissor　--> scissor wins 

while True:
print('Now please enter your choice no. 
　1. Rock 
　2. paper 
　3. scissor 

# take the input from user
ch = int(input('Now Your turn: '))
while ch >　3　or ch <　1:
　　　ch = int(input('Enter your valid input here: '))
if ch ==　1:
　　　choice_name = 'Rock'
elifch ==　2:
　　　choice_name = 'paper'
else:
　　　choice_name = 'scissor'
# print user given choice
　　　print("Your choice is: "　+　choice_name)
print("\nNow its computer turn to initiate.......")
# Computer will select randomly any number
# among values　1,　2　and　3. Using randint method
# of random module
comp_choice = random.randint(1,　3)
# looping will continue until comp_choice value
# is equal to the choice value
while comp_choice == ch:
comp_choice = random.randint(1,　3)
# initialize value of the variable comp_choice_name
# variable corresponding to the choice value
if comp_choice ==　1:
　　　comp_choice_name = 'Rock'
elif comp_choice ==　2:
　　　comp_choice_name = 'paper'
else:
　　　comp_choice_name = 'scissor'
　　　print("So computer choice is: "　+　comp_choice_name)
print(choice_name　+　" V/s "　+　comp_choice_name)
　　　# condition for winning the game
if((ch ==　1　and comp_choice ==　2) or
　　　(ch ==　2　and comp_choice ==1　)):
print("paper wins =>", end = ")")
　　　final_result = "paper"
elif((ch ==　1　and comp_choice ==　3) or
　　　(ch ==　3　and comp_choice ==　1)):
print("Rock wins =>", end = ")")
　　　final_result = "Rock"
else:
　　　print("scissor wins =>", end = ")")
　　　final_result = "scissor"
　　　# Printing either user or computer wins
if final_result == choice_name:
　　　print("<== You are the winner ==>")
else:
　　　print("<== Computer wins ==>")
　　　　　　print("Do you want to play again? (Y/N)")
　　　　　　ans = input()  # if user input n or N then condition is True
if ans == 'n' or ans == 'N':
　　　break
　　　# after exiting from the while loop
print("\nThanks for sharing time with us...")

Output result

The rules of Rock paper scissor game will be follows:
Rock vs paper　--> paper wins
Rock vs scissor　--> Rock wins
paper vs scissor　--> scissor wins
Now please enter your choice number.
1. Rock
2. paper
3. scissor
Now Your turn:　1
Your choice is: Rock
Now its computer turn to initiate.....
So computer choice is: paper
Rock V/s paper
paper wins =><== Computer wins ==>
Do you want to play again? (Y/N)
y
Now please enter your choice number.
1. Rock
2. paper
3. scissor
Now Your turn:　2
Your choice is: paper
Now its computer turn to initiate.....
So computer choice is: Rock
paper V/s Rock
paper wins =><== You are the winner ==>
Do you want to play again? (Y/N)
n
