我花了很长时间试图找出这个问题，我需要一双新鲜的眼睛和一个对python有所了解的人。
我开始实施一个国际象棋游戏，以帮助我学习python，我基本上只实现移动的棋子和显示板。这是问题所在：
- 当我将任何顶级球员的棋子向前移动1或2个空格时，一切都很好。
- 当我将任何一名底层球员的棋子向前移动时，一切都很好。
- 当我将任何一名底层球员的棋子向前移动时，一切都会出错。在显示器上，新位置的整行变成了棋子，但是在打印结果之后，所有空位现在都“属于”底部玩家（他们应该属于没有人，0）。
我尝试使用相同的结果测试不同的列。
以下是该问题的说明：

??不行吗？ - （移动后，所有'空白'空格属于底部玩家，所有第6行（如下所示）都将类型变量设置为pawn）
Enter a move [r0,c0,r1,s1]: [7,a,6,a]

评论这些内容：
board.Board[row1][col1].Sym = board.Board[row0][col0].Sym
board.Board[row1][col1].Id = board.Board[row0][col0].Id
board.Board[row1][col1].Player = board.Board[row0][col0].Player
使它基本上什么都不做，所以我想你可以说这就是问题所在，但它适用于相反的玩家，而且它是相同的代码，所以这就是为什么我不确定问题是否真的存在在这些方面。
非常感谢任何帮助。

我采取完全不同的方法，而不是使用板来存储位置和空白件，我会将位置信息存储在32 {{1}在安装时生成并仅使用Piece类来存储片段列表并执行Board
e.g。一些事情：
Board.draw()
