为什么 win_check 功能不能正常工作？

Question

我是新手，我在 python 中创建了一个井字游戏，我制定了逻辑，但代码没有按预期运行我尝试调试它，但找不到错误。

我是 python 新手，并在课程中学习 udemy 课程，起初我被要求自己编写一个井字游戏。我想出了一个不太好的逻辑，但它会完成这项工作。我只是无法弄清楚为什么 win_check 功能无法正常工作。是 win_check 函数还是别的什么？对改进我的代码有什么建议？ 很抱歉没有在代码中提供 cmets 我只是想先完成它并成功运行它。

运行代码时没有错误。

Answer 1

您面临的问题在于 win_check。 win_check 执行以下步骤：

1. 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"_"
2. 它检查第二个玩家是否获胜，并将变量 game_status 设置为"Player X wins"，或"Player Y wins"，或"_"
3. 它检查是否发生了平局并将变量 game_status 设置为"game draws" 或"_"

在每一步之后，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，它将更具可读性和功能正确性。 我还会将检查玩家是否获胜的检查转移到自己的名为has_won 的函数中，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 = "_"
