Write a function that plays the popular scissor-rock-paper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper can wrap a rock.) Function prototype: void gameOfScissorRockPaper(int) The function randomly generates a number 0, 1, or 2 representing SCISSOR, ROCK, and PAPER. It prompts the user to enter a number 0, 1, or 2 and displays messages indicating the choices from the user and computer, whether the user or the computer wins, loses, or draws. If the user enters an invalid choice, prompt an error message, and ask to re-enter the choice. The function takes one int argument specified how many FIRST wins from the computer or the user to win the game. It will let the user continuously play until either the user or the computer wins. Use enum to define Inputs values as below to check the user's input in your program,

Answer:

Python Code:

# import random module  

import random  

# Print multiline instruction  

# performstring concatenation of string  

print("Winning Rules of the Rock paper scissor game as follows: \n"

       +"Rock vs paper->paper wins \n"

       + "Rock vs scissor->Rock wins \n"

       +"paper vs scissor->scissor wins \n")  

while True:  

print("Enter choice \n 1. Rock \n 2. paper \n 3. scissor \n")  

 

# take the input from user  

choice = int(input("User turn: "))  

# OR is the short-circuit operator  

# if any one of the condition is true  

# then it return True value  

 

# looping until user enter invalid input  

while choice > 3 or choice < 1:  

 choice = int(input("enter valid input: "))  

 

# initialize value of choice_name variable  

# corresponding to the choice value  

if choice == 1:  

 choice_name = 'Rock'

elif choice == 2:  

 choice_name = 'paper'

else:  

 choice_name = 'scissor'

 

# print user choice  

print("user choice is: " + choice_name)  

print("\nNow its computer turn.......")  

# Computer chooses randomly any number  

# among 1 , 2 and 3. Using randint method  

# of random module  

comp_choice = random.randint(1, 3)  

 

# looping until comp_choice value  

# is equal to the choice value  

while comp_choice == choice:  

 comp_choice = random.randint(1, 3)  

# initialize value of 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("Computer choice is: " + comp_choice_name)  

print(choice_name + " V/s " + comp_choice_name)  

# condition for winning  

if((choice == 1 and comp_choice == 2) or

(choice == 2 and comp_choice ==1 )):  

 print("paper wins => ", end = "")  

 result = "paper"

 

elif((choice == 1 and comp_choice == 3) or

 (choice == 3 and comp_choice == 1)):  

 print("Rock wins =>", end = "")  

 result = "Rock"

else:  

 print("scissor wins =>", end = "")  

 result = "scissor"

# Printing either user or computer wins  

if result == choice_name:  

 print("<== User wins ==>")  

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 coming out of the while loop  

# we print thanks for playing  

print("\nThanks for playing")
