实例没有属性__getitem__

Question

我正在研究基于web2py生活游戏的生活模拟游戏。我有两个对象，其中包含几个数组，用于网格中每个空间中有机体的各种属性。我收到此错误LifeSpace实例在包含此代码的行上没有属性“ getitem ”nxt [i] [j] = processNeighborsEmpty（i，j，cur）

我是否正确引用了对象实例？

ROWS = 60
COLS = 60
GENERATIONS = 100
DELAY = 0.5

Answer 1

nxt是LifeSpace对象，因此您无法使用[]表示法引用它。

您需要使用具有正确属性的nxt.attribute[x][y]。也许nxt.genux[x][y]是您想要使用的。
