Conway's Game of Life(康威生命游戏)Python实现细胞无法死亡求助

问题定位 #

你的代码存在两处核心错误：

• 状态更新逻辑误用了相等判断符==代替赋值符=
• time.sleep(1)的缩进位置错误，导致运行时序不符合预期

错误详情 #

你在更新next数组的后两个分支里，用了==（判断两个值是否相等），而没有用=（给变量赋值）：

# 错误写法
elif current[x][y] == " " and neighbors == 3:
    next[x][y] == "#" # 此处为相等判断，不会修改变量值
else:
    next[x][y] == " " # 此处为相等判断，不会修改变量值

这就导致只有原本存活、且符合存活条件（邻居数为2或3）的细胞会被正确赋值为#，其余所有情况都不会修改next数组的原有值，自然就出现了活细胞永远不会被改为空格、也就是永不死亡的问题。

另外time.sleep(1)现在缩进在x轴循环内部，每处理完1列就会暂停1秒，正确应该放在所有状态更新逻辑结束后，也就是两层遍历x、y的for循环外面，每完成一代更新再暂停。
额外提示：next是Python内置函数名，不建议用作自定义变量名，避免后续调用内置函数时出现异常。
