Question

I need the create a Python code that makes a two-player Rock-Paper-Scissors game. (Hint: Ask for player plays (using input), compare them, print out a message of congratulations to the winner, and ask if the players want to start a new game)

Please help me see why my "continue" is asking the players to start a new game.

Here is my code;

user1= input("Whats your name? ")
user2= input("And your name? ")
a = input("%s, do yo want to choose rock, paper or scissors? " % user1)
b = input("%s, do you want to choose rock, paper or scissors? " % user2)

def compare(a, b):
if a=='rock':
if b=='rock':
return"Tie"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='paper':
return "paper wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='scissors':
return"rock wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif a=='paper':
if b=='rock':
return"paper wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='paper':
return "tie"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='scissors':
return"scissors wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif a=='scissors':
if b=='rock':
return"rock wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='paper':
return "scissors wins"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break
  
elif b=='scissors':
return"tie"
if str(input('Do you want to play another game, yes or no?\n')) == 'yes':
continue
else:
print('Game Over.')
break

print(compare(a,b))

Answer 1

Program:

def compare(a, b):
   if a == 'rock':
       if b == 'rock':
           return "Tie"
       elif b == 'paper':
           return "paper wins"
       elif b == 'scissors':
           return "rock wins"

   elif a == 'paper':
       if b == 'rock':
           return "paper wins"
       elif b == 'paper':
           return "Tie"
       elif b == 'scissors':
           return "scissors wins"

   elif a == 'scissors':
       if b == 'rock':
           return "rock wins"
       elif b == 'paper':
           return "scissor wins"
       elif b == 'scissors':
           return "Tie"
  

user1= input("Whats your name? ")
user2= input("And your name? ")

while True:
   a = input("%s, do yo want to choose rock, paper or scissors? " % user1)
   b = input("%s, do you want to choose rock, paper or scissors? " % user2)
   print(compare(a,b))
   if str(input('Do you want to play another game, yes or no?\n')) != 'yes':
       print("Game Over.")
       break

Answer 2

Please find the modified code below.

CODE

def compare():

while True:

user1= input("Whats your name? ")

user2= input("And your name? ")

a = input("%s, do yo want to choose rock, paper or scissors? " % user1)

b = input("%s, do you want to choose rock, paper or scissors? " % user2)

if a=='rock':

if b=='rock':

print ("Tie")

elif b=='paper':

print ("paper wins")

elif b=='scissors':

print ("rock wins")

elif a=='paper':

if b=='rock':

print ("paper wins")

elif b=='paper':

print ( "tie")

elif b=='scissors':

print ("scissors wins")

elif a=='scissors':

if b=='rock':

print ("rock wins")

elif b=='paper':

print ( "scissors wins")

elif b=='scissors':

print ("tie")

cont = input('Do you want to play another game, yes or no?\n')

if cont.lower() != 'yes':

print('Game Over.')

break

compare()
