Python 为什么我的数组编辑不能正常工作？

我是Python的初学者，正在制作一个棋盘游戏，玩家可以在其中输入他们想要左/右移动的位置等。但是有时它移动正确，有时不正确。我想这和我的网格阵列有关，但我不确定。。。如果有人能帮我，那就太好了，谢谢

我已经附上了我的所有代码，包括验证，这样用户就不会逃出网格，因为我不确定要包括哪些部分来明确我的问题和程序。

实践改进：

这里有一个关于调试的精彩介绍

我强烈推荐增量编程：编写几行代码，确保它们正常工作，直到现有代码正确无误后再继续。这样，当某些东西不起作用时，你知道它在你添加的最后几行。否则，您将得到200行代码，而不知道错误在哪里

节目更改

此代码不是为调试或维护而设计的；你应该在继续之前解决这些问题。最重要的是，您创建了两组执行一个任务（获取用户移动）的输入，然后创建了四个执行相同任务（移动用户）的代码块

相反，找到一些有用的措辞，让玩家在一行上输入移动。将其转换为移动坐标（例如[1，-2]表示“向上一个，向左两个”），然后使用一个代码块在网格中移动。测试一个代码块，而不是测试四个代码块；当您需要进行更改时，只需进行一次更改，而不是在旋转和反射下进行四次复制

结果 您使用的代码应该更像这样：

def get_move():
    advice  = "Please enter your move in two integers:\n" +
              "vertical, then horizontal.  Use positive numbers\n" +
              "for up and right, negative for down and left.\n"
    example = "For instance, the line \n\t2 -1\n" +
              "   is 2 spaces up, one space left."
    move = input(advice + example).split
    x_move = int(move[0])
    y_move = int(move[1])
    # Here, you check move legality; repeat until you get a legal move

    return x_move, y_move

while True:
    print_board()
    x_move, y_move = get_move()    # get_move contains the input interaction and data checking
    move(x_move, y_move)  # perform the move; update the board.

还请注意，您可能应该更新现有的板，而不是（显然）为每个移动创建一个新的板。在游戏结束之前，保持这个循环；不要在每一个动作上都爆发

这是否会促使您找到解决方案？

“我是Python的初学者…”-住手！你需要后退几步。像这样的项目不是初学者应该尝试做的。试着做一些类似于抽搐的动作，然后向上移动。@leaf绝对正确，有点冒险！然而，我认为这是一个网站上的初学者挑战，我真的希望完成它定义“初学者”。这是指初学者，比如刚刚下载Python，或者我已经做了几个月的Python初学者。现在，我看到的代码最大的问题是它非常冗长；yi2=int（yi2向下）。保持一致，使错误更加明显。例如，您总是可以向左和向下减去，向右和向上相加。通过这种方式，您将回顾您的逻辑，并使其在将来更容易理解。此外，试着看看你是否能找到一个模式，以确定它何时起作用，何时不起作用。它总是朝一个方向吗？它是否接近边缘？我强烈建议增量编程：编写几行代码，确保它们正常工作，在现有代码正确之前不要继续。这样，当某些东西不起作用时，你知道它在你添加的最后几行。否则，您将得到200行代码，而不知道错误在哪里。“我是Python的初学者…”-停止！你需要后退几步。像这样的项目不是初学者应该尝试做的。试着做一些类似于抽搐的动作，然后向上移动。@leaf绝对正确，有点冒险！然而，我认为这是一个网站上的初学者挑战，我真的希望完成它定义“初学者”。这是指初学者，比如刚刚下载Python，或者我已经做了几个月的Python初学者。现在，我看到的代码最大的问题是它非常冗长；yi2=int（yi2向下）。保持一致，使错误更加明显。例如，您总是可以向左和向下减去，向右和向上相加。通过这种方式，您将回顾您的逻辑，并使其在将来更容易理解。此外，试着看看你是否能找到一个模式，以确定它何时起作用，何时不起作用。它总是朝一个方向吗？它是否接近边缘？我强烈建议增量编程：编写几行代码，确保它们正常工作，在现有代码正确之前不要继续。这样，当某些东西不起作用时，你知道它在你添加的最后几行。否则，你
