Python Rock Paper Scissors游戏（在特定条件下循环播放）

Question

我制作了一个简单的Rock Paper Scissors程序，并且需要在该程序中添加一定的条件。.我必须让用户连续播放，直到用户或计算机连续赢得两次以上。出入答案，但不幸的是找不到。

首先我尝试过

 gameOver = False
 playerScore = 0
 computerScore = 0

并添加

while not gameOver:
    main()
    if playerScore == 2 :
        gameOver = True

并在if语句中添加了playerScore + = 1 。
但是行不通...
任何建议将有所帮助，并在此先感谢。

这是我的代码。

import random
import sys


def main():
    player = input("Enter your choice in number (rock 1 / paper 2 / scissors 0) :")


    if (player == 0):
        player = "scissors"
    elif (player == 1):
        player = "rock"
    elif (player == 2):
        player = "paper"
    else:
    print("Invalid Input Quitting...")
    sys.exit(0)


    computer = random.randint(0,2)
    if (computer == 0):
        computer = "scissors"
    elif (computer == 1):
        computer = "rock"
    elif (computer == 2):
        computer = "paper"





    if (player == computer):
        print("Player is ",player, "Computer is ",computer," You Draw!")

    elif (player == "rock"):
        if (computer == "paper"):
            print("Player is ",player, "Computer is ",computer," You Lost!")


        else:
            print("Player is ",player, "Computer is ",computer," You Win!")



    elif (player == "paper"):
        if (computer == "rock"):
            print("Player is ",player, "Computer is ",computer," You Win!")


        else:
            print("Player is ",player, "Computer is ",computer," You Lost!")


    elif (player == "scissors"):
        if (computer == "rock"):
            print("Player is ",player, "Computer is ",computer," You Lost!")


        else:
            print("Player is ",player, "Computer is ",computer," You Win!")

Answer 1

如果您的main()函数返回与获胜者相对应的值，则可以执行以下操作：

gameOver = False
playerScore = 0
computerScore = 0

while not gameOver:
    player_wins = main()
    if player_wins == True:
        playerScore += 1
        computerScore = 0
    if player_wins == False:
        playerScore = 0
        computerScore += 1
    if player_wins == None:
        # Draw, do nothing to the scores
        pass
    if playerScore == 2 or computerScore == 2:
        print("Game over")
        print("  playerScore:", playerScore)
        print("  computerScore:", computerScore)
        gameOver = True

请注意，如果玩家获胜，则返回True如果计算机获胜，则返回False如果平局，则返回None 。

Answer 2

我认为您只是在问一个模式：（这不是真实的代码）

Program starts:
gameover = False
lastWinner = ""
Loop until gameover == True
    ask for player answer
    make the random choice of the computer
    winner = "asigned winner"
    if lastWinner == winner:
        gameover = True
        Print something cool about who is the winner
    else:
        lastWinner = winner

Answer 3

尝试修改全局变量时，您可能会遇到错误，但是从您的示例中尚不清楚。 如果您尝试在main（）方法中修改playerScore或computerScore ，除非您有类似以下语句，否则它会大吼大叫：

global computerScore

在您修改它之前。

另外，避免在代码中重复自己。 通过使用以下命令，我能够裁剪掉大部分代码：

computerWins = False

print "Player is %s; Computer is %s" % (computer, player)

if (player == computer):
  print "Draw"
  return 0
elif (player == "rock"):
  computerWins = computer == "paper"
elif (player == "paper"):
  computerWins = computer == "scissors"
elif (player == "scissors"):
  computerWins = computer == "rock"

if computerWins:
  global computerScore
  computerScore = computerScore + 1
  print "Computer wins"
else:
  global playerScore
  playerScore = playerScore + 1
  print "You win"
