Question

我的其余代码完成了我现在想做的事情。我不能为我的生活弄清楚为什么我不能在玩家之间切换。我的代码对我有意义。这是一个由两部分组成的问题：我如何使用我采用的相同方法解决这个问题，以及你将如何做到这一点？

Answer 1

这里实际上存在多个问题，但让我们来看看它的根源：

winning_combo功能会在每次通话开始时重置turn = 0。当然，您使用turn = (turn + 1) % len(players)将其更新为1，但您永远不会再次使用该值;您只需从函数返回，然后再次调用它，然后再次设置turn = 0。

这里最简单的解决方法是为turn使用全局变量，因此它可以在调用之间保持持久性：

def winning_combo(player1, player2):
    global turn
    players = [player1, player2]
    player = players[turn]
    turn = (turn + 1) % len(players)
    while tiles_available:
        # the rest of the code is the same

def game():
    global turn
    turn = 0
    playing = True
    # the rest of the code is the same

您可能听说全局变量很糟糕。你能在这里避开吗？当然。虽然你不能在winning_combo中使用局部变量，因为该函数不断退出并重新开始，你可以使用game中的局部变量，并将其传入作为参数到winning_combo：

def winning_combo(player1, player2, turn):
    players = [player1, player2]
    player = players[turn]
    while tiles_available:
        move = int(input('Where would you like to move? '))
        # the rest of the code is the same

def game():
    turn = 0
    playing = True
    player1, player2 = player_input()
    while playing:
        draw_board()
        winning_combo(player1, player2, turn)
        turn = (turn + 1) % 2
        win_combo()

还有很多其他方法可以改进你的设计并简化你的代码，并修复错误（例如，当游戏结合时会发生什么？），但这应该会让你超越当前的bug，并希望能给你深入了解局部变量的工作原理。
