我能做些什么来修复我的石头剪刀布代码以保持分数并结束游戏

Question

Here's my code for a Rock, Paper, Scissors game and I am confused on how to create a running score as well as a way to end the game once the user enters 0.

import random

def main():
  print ("Welcome to the Rock, Paper, Scissors Tournament!")
  computerTotal = 0
  playerTotal = 0
  playerChoice = playerSelection()
  while (playerChoice != 0):
      computerChoice = computerSelection()
      winner = roundWinner()
      if (winner == 'computer'):
          computerTotal = computerTotal + 1
      elif (winner == 'player'):
          playerTotal = playerTotal + 1
      playerChoice = playerSelection()
      matchWinner = (computerTotal, playerTotal)


def computerSelection():
    choice = random.randint(1,3)
    if choice == 1:
      print ("Computer chose rock")
    elif choice == 2:
      print ("Computer chose scissors")
    elif choice == 3 :
      print ("Computer chose paper")
    return choice

def playerSelection():
    choice = input ("Enter 1 for rock, 2 for scissors, 3 for paper (0 to end the Tournament): ")
    if choice == 0:
      print  ('Final score:', matchWinner() )
    elif choice == 1:
      print ('Player chose rock')
    elif choice == 2:
      print ('Player chose scissors')
    elif choice == 3:
      print ("Player chose paper")
    return playerSelection

def roundWinner():
  if playerSelection() == computerSelection():
    print("Draw no one wins!")
  elif playerSelection == 1 and computerSelection == 3:
    print("Computer Wins!")
  elif playerSelection == 1 and computerSelection == 2:
    print("Player Wins!")
  elif playerSelection == 3 and computerSelection == 1:
    print("Player Wins!")
  elif playerSelection == 3 and computerSelection == 2:
    print("Computer Wins!")
  elif playerSelection == 2 and computerSelection == 1:
    print("Computer Wins!")
  elif playerSelection == 2 and computerSelection == 3:
    print("Player Wins!")


def matchWinner():
  if computerTotal > playerTotal :
    print (" Computer wins the game!" )
  elif computerTotal == playerTotal:
    print (" Draw no one wins!" )
  elif computerTotal < playerTotal:
    print (" Player wins the game!" )

I want to also display the match winner once the user has typed 0 and the game has ended.

Answer 1

Your loop is bad.

• Remove : computerChoice = computerSelection() and playerChoice = playerSelection() because they are calculated in roundWinner . Your are actually doing 2 plays per loop.

• Unindent : matchWinner(computerTotal, playerTotal)

while True:
    winner = roundWinner()
    if (winner == 'computer'):
        computerTotal = computerTotal + 1
    elif (winner == 'player'):
        playerTotal = playerTotal + 1
    elif (winner == 'exit'):
        break
matchWinner(computerTotal, playerTotal)

Also fix roundWinner to return 'exit' in case player pressed 0. In that case, the exit decision should rise up to all higher functions.

Answer 2

I've tried changing a bit your code and it didn't really go well, I'd suggest you to use less functions next time in cases like that, it will make your life easier. Anyway, I took your code (with a few minor changes) and put it all in one function.

import random
def RPS():
    computerTotal = 0
    playerTotal = 0
    playerChoice = input ("Enter 1 for rock, 2 for scissors, 3 for paper (0 to end the Tournament): ")
    while (playerChoice != 0):
        computerChoice = random.randint(1,3)

        #Prints R/P/S of player & computer.

        if computerChoice == 1:
            print ("Computer chose rock")
        elif computerChoice == 2:
            print ("Computer chose scissors")
        elif computerChoice == 3 :
            print ("Computer chose paper")
        if playerChoice == 1:
            print ('Player chose rock')
        elif playerChoice == 2:
            print ('Player chose scissors')
        elif playerChoice == 3:
            print ("Player chose paper")

        #Calculating & printing who won(the round)

        if playerChoice == computerChoice:
            print("Draw no one wins!")
        elif playerChoice == 1 and computerChoice == 3:
            print("Computer Wins!")
            computerTotal = computerTotal + 1
        elif playerChoice == 1 and computerChoice == 2:
            print("Player Wins!")
            playerTotal = playerTotal + 1
        elif playerChoice == 3 and computerChoice == 1:
            print("Player Wins!")
            playerTotal = playerTotal + 1
        elif playerChoice == 3 and computerChoice == 2:
            print("Computer Wins!")
            computerTotal = computerTotal + 1
        elif playerChoice == 2 and computerChoice == 1:
            print("Computer Wins!")
            computerTotal = computerTotal + 1
        elif playerChoice == 2 and computerChoice == 3:
            print("Player Wins!")
            playerTotal = playerTotal + 1

        playerChoice = input ("Enter 1 for rock, 2 for scissors, 3 for paper (0 to end the Tournament): ")

      #if we got here means the player entered 0. printing who won the game
    if computerTotal > playerTotal :
        print (" Computer wins the game!" )
    elif computerTotal == playerTotal:
        print (" Draw no one wins!" )
    elif computerTotal < playerTotal:
        print (" Player wins the game!" )

As you can see, I didn't use a function to run the player Selection and I made it so whenever you enter 0 it will break the loop and show the results.
