Question

我是新手，我用python创建了一个tic tac toe toe游戏，我弄清楚了逻辑，但是代码没有按预期的方式运行，但是我尝试调试它但找不到错误。

我是python的新手，刚开始我被要求自己编写tic tac toe游戏的过程是关于udemy的课程。我已经找到了一个不太好的逻辑，但是它可以完成工作。我只是不知道为什么win_check函数不能正常工作。是win_check函数还是其他？对改进我的代码有什么建议？抱歉，我没有在代码中给出注释，我只是想先完成并成功运行它。

运行代码时没有错误。

您面临的问题在于win_check。 win_check执行以下步骤：

它检查第一个玩家是否获胜，并将变量game_status设置为"Player X wins"或"Player Y wins"或"_"
它检查第二位玩家是否获胜，并将变量game_status设置为"Player X wins"或"Player Y wins"或"_"
它检查是否发生平局，并将变量game_status设置为"game draws“或"_"

每一步之后，它都会删除最后一步的结果。

如果您使用单个if和elif链来管理控制流，那么它将更具可读性和功能上的正确性。我还将检查玩家是否赢得了has_won自己的功能，这将提高可读性并减少代码重复。

def win_check(board, player_1, player_2):
    global game_status
    if has_won(board, player_1):
        game_status = "Player " + player_1 + " has won"
    elif has_won(board, player_2):
        game_status = "Player " + player_2 + " has won"
    elif is_draw(board):
        game_status = "Game draws"
    else:
        game_status = "_"

为什么win_check函数不能正常工作？
