Python es un lenguaje multipropósito y uno puede hacer cualquier cosa con él. Python también se puede utilizar para el desarrollo de juegos. Vamos a crear un juego de piedra, papel o tijera de línea de comandos simple sin usar bibliotecas de juegos externas como PyGame. En este juego, el usuario tiene la primera oportunidad de elegir la opción entre piedra, papel y tijera. Después de que la computadora seleccione de las dos opciones restantes (al azar), el ganador se decide según las reglas.
Winning Rules as follows : Rock vs paper-> paper wins Rock vs scissor-> Rock wins paper vs scissor-> scissor wins.
En este juego, la función incorporada randint() se usa para generar valores enteros aleatorios dentro del rango dado.
A continuación se muestra la implementación:
Python3
# 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 for Rock, \n 2 for paper, and \n 3 for 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)
#we need to check of a draw
if choice == comp_choice:
print("Draw=> ", end = "")
result = Draw
# 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 or draw
if result == Draw:
print("<== Its a tie ==>")
if result == choice_name:
print("<== User wins ==>")
else:
print("<== Computer wins ==>")
print("Do you want to play again? (Y/N)")
ans = input().lower
# if user input n or N then condition is True
if ans == 'n':
break
# after coming out of the while loop
# we print thanks for playing
print("\nThanks for playing")

winning Rules of the Rock paper and scissor game as follows: rock vs paper->paper wins rock vs scissors->rock wins paper vs scissors->scissors wins Enter choice 1. Rock 2. paper 3. scissor User turn: 1 User choice is: Rock Now its computer turn....... computer choice is: paper Rock V/s paper paper wins =>computer wins do you want to play again? N
