复制没有相同 id 的类数组

Question

我正在做康威的生命游戏。 有两件事是错误的。

1. 出于某种原因，动画代码正在接收网格信息但未正确绘制它，只为所有单元格显示一个值。这以前有效，但我对 matplotlib 了解不多，所以我找不到问题所在。
2. 我需要找到一种方法使我的网格相等但不连接，即何时更新一个我不希望另一个更改。 [我认为我做错了什么在第 91 行]

我认为这里的问题是您正在制作“浅拷贝”，而不是“深拷贝”。请参阅here 了解更多信息。

作为修复，请尝试导入副本：

import copy

并将第 91 行更改为：

self.grid_1 = copy.deepcopy(self.grid_2)
