所以我在python中创造了conway的生活游戏。规则是
活动邻居少于两个的活细胞死亡 任何有两三个活邻居的活细胞都会留在下一代。 任何有三个以上活邻居的活细胞都会死亡。 任何有三个活邻居的死细胞都会成为活细胞。
我无法弄清楚为什么首先，我的liveNeighbors计数器有时打印错误，而且电路板永远不会改变。

答案 0 :(得分：2)
您正在检查相等性，而不是在nextIteration函数的这部分中进行分配：
if newBoard[row][column] == "X":
if liveNeighbors < 2 or liveNeighbors > 3:
board[row][column] == "0" # Here
if newBoard[row][column] == "0":
if liveNeighbors == "3":
board[row][column] == "X" # And here
board[row][column] == "0"应为board[row][column] = "0"等。目前，该行评估为True，然后该值立即被丢弃，并且不会发生状态更改。
