python - 我有一个代码应该用 O 替换字符串中的随机点

Question

def getCSpot():
    global board
    global cspot
    spotchosen = False
    while spotchosen == False:
        spotchosen = False
        cspot = random.randint(0, 8)
        if board[cspot] == 'X' or board[cspot] == 'O':
            cspot = random.randint(0, 8)            
        else:
            spotchosen = True
            board[cspot] = 'O'

我真的不明白为什么这不起作用。它根本不会将 O 放入字符串中。我有另一部分代码确定当连续有 3 个 O 或 X 时是否有赢家，这也不起作用，这是该代码。任何帮助深表感谢。

def didwin(player):
    global gameOver
    if (board[0] == player and board[1] == player and board[2] == player or
            board[3] == player and board[4] == player and board[5] == player or
            board[6] == player and board[7] == player and board[8] == player or 
            board[0] == player and board[3] == player and board[6] == player or
            board[1] == player and board[4] == player and board[7] == player or
            board[2] == player and board[5] == player and board[8] == player or 
            board[0] == player and board[4] == player and board[8] == player or
            board[2] == player and board[4] == player and board[6] == player):
        gameOver = True
        if player == 'X':
            print 'congratulations! You won!!'
            endGame()
        else:
            print 'Better luck next time, you lost!'
            endGame()

出于参考目的，这里是 endGame 函数。

def endGame():
    global board
    displayBoard()
    answer = ' '
    while answer == ' ':
        print 'Would you like to play another game?'
        answer = raw_input('Y/N')
    if answer == 'Y' or answer == 'y' or answer == 'Yes' or answer == 'yes':
        board = [0, 1, 2, 3, 4, 5, 6, 7, 8]
        game1()
        game()
    elif answer == 'N' or answer == 'n' or answer == 'No' or answer == 'no':
        exit()

编辑：以下是我的整个代码，从头到尾没有编辑。

board = [0, 1, 2,
           3, 4, 5,
           6, 7, 8]

    print board[0], '|', board[1], '|', board[2]
    print '----------'
    print board[3], '|', board[4], '|', board[5]
    print '----------'
    print board[6], '|', board[7], '|', board[8]
def getspot():

    spotchosen = False
    while spotchosen == False:
        spotchosen = False
        playerSpot = int(raw_input('Where would you like to go? '))
        if board[playerSpot] != 'X':
            board[playerSpot] = 'X'
        if board[playerSpot] != 'O':
            board[playerSpot] = 'X'

Answer 1

我很确定，无论是什么问题，都存在于您没有向我们展示的代码中。

endGame为了简单起见，我没有测试您的功能。但是我粘贴了您的其他代码，并添加了以下内容：

board = [0, 1, 2, 3, 4, 5, 6, 7, 8]
gameOver = False
def endGame():
    print 'endGame called'
for i in range(9):
    getCSpot()
    print(board)
    didwin('O')
    if gameOver:
        print 'gameOver'
        break

结果是：

[0, 'O', 2, 3, 4, 5, 6, 7, 8]
[0, 'O', 2, 3, 'O', 5, 6, 7, 8]
[0, 'O', 2, 3, 'O', 5, 'O', 7, 8]
[0, 'O', 2, 3, 'O', 5, 'O', 'O', 8]
Better luck next time, you lost!
endGame called
gameOver

当然序列是随机的，所以每次都不完全相同，但它总是一次用“O”替换一个随机数，直到有一个 3-in-a-row，然后告诉我我输了。

因此，它完全按预期工作。如果您的代码不起作用，则说明您做错了其他事情。也许您正在设置board或初始设置中有其他错误？

添加你的displayBoard和endGame代码，它会一直工作，直到你说'y'来玩另一个游戏，此时它会调用一些名为但不存在的函数，从而game1引发.gameNameError

我还在你的 start 函数中看到（从你删除的评论中，所以这是从内存中看到的）你正在调用一个getspot()在游戏循环中调用的函数，而不是调用getCSpot(). 如果getspot在某处定义，则问题可能是您有一个正确的功能和一个不正确的功能。或者它可能没有在任何地方定义，并且“不工作”和“根本没有把 O 放在字符串中”你的意思是“没有被调用，因为在我有机会之前游戏停止了异常” ?

现在您已经发布了整个内容，但存在一些明显的问题。

首先，你永远不会getCSpot在任何地方打电话。这就是为什么它什么都不做。大概你想要这个：

def mainGame():
    gameOver = False
    while gameOver == False:
        displayBoard()
        getspot()
        didwin('X')
        didwin('O')
        getCSpot()
        didwin('X')
        didwin('O')

此外，在 中getspot，您的if陈述都是错误的。如果 ，您将允许移动board[playerSpot] != 'X'，如果 也允许移动board[playerSpot] != 'O'- 换句话说，总是。然后你将把玩家算作移动，除非playerSpot == 'O'它是假的——它总是这样，因为它应该是一个数字。

我想你想要这个：

    if board[playerSpot] == 'X':
        playerSpot = raw_input('You have already chosen that spot. Please choose another. ')
    elif board[playerSpot] == 'O':
        playerSpot = raw_input('The computer chose that spot already. Please choose another. ')
    else:
        board[playerSpot] = 'X'
        spotchosen = True
