python - 如何检查一个数字是否在列表列表中？

Question

所以我一直无法检查数字 0 是否在另一个列表中的一组列表中。这些行构成了我正在制作的吃 bean 人类型游戏的迷宫，所以这样做的目的是检查吃 bean 人是否吃掉了所有硬币。

这是我的代码:

row1 =[3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3]
row2 =[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]
row3 =[1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1]
row4 =[1,0,1,1,0,1,1,1,0,1,0,1,1,1,0,1,1,0,1]
row5 =[1,0,1,1,0,1,1,1,0,1,0,1,1,1,0,1,1,0,1]
row6 =[1,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,1]
row7 =[1,0,1,1,0,1,0,1,1,1,1,1,0,1,0,1,1,0,1]
row8 =[1,0,0,0,0,1,0,1,1,1,1,1,0,1,0,0,0,0,1]
row9 =[1,1,1,1,0,1,0,0,0,1,0,0,0,1,0,1,1,1,1]
row10=[3,3,3,1,0,1,1,1,0,1,0,1,1,1,0,1,3,3,3]
row11=[3,3,3,1,0,1,0,0,0,0,0,0,0,1,0,1,3,3,3]
row12=[3,3,3,1,0,1,0,1,4,4,4,1,0,1,0,1,3,3,3]
row13=[1,1,1,1,0,1,0,1,3,3,3,1,0,1,0,1,1,1,1]
row14=[3,3,3,3,0,0,0,1,3,3,3,1,0,0,0,3,3,3,3]
row15=[1,1,1,1,0,1,0,1,5,5,5,1,0,1,0,1,1,1,1]
row16=[3,3,3,1,0,1,0,3,3,3,3,3,0,1,0,1,3,3,3]
row17=[3,3,3,1,0,1,0,1,1,1,1,1,0,1,0,1,3,3,3]
row18=[3,3,3,1,0,1,0,1,1,1,1,1,0,1,0,1,3,3,3]
row19=[1,1,1,1,0,0,0,0,0,1,0,0,0,0,0,1,1,1,1]
row20=[1,0,0,0,0,1,1,1,0,1,0,1,1,1,0,0,0,0,1]
row21=[1,0,1,1,0,0,0,0,0,3,0,0,0,0,0,1,1,0,1]
row22=[1,0,1,1,0,1,0,1,1,1,1,1,0,1,0,1,1,0,1]
row23=[1,2,0,0,0,1,0,0,0,1,0,0,0,1,0,0,0,2,1]
row24=[1,0,1,1,1,1,1,1,0,1,0,1,1,1,1,1,1,0,1]
row25=[1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1]
row26=[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]

maze = [row1,row2,row3,row4,row5,row6,row7,row8,row9,row10,row11,row12,
        row13,row14,row15,row16,row17,row18,row19,row20,row21,row22,
        row23,row24,row25,row26]

所以我尝试了 if 0 not in maze: 但是无论 0 是否在(迷宫)中，if 语句都会执行。

如有任何帮助，我们将不胜感激。

你必须遍历 maze 中的每个列表并检查是否有 0:

if not any(0 in i for i in maze):
    ...

关于 any() 的伟大之处功能是一旦找到 0，它就会停止在 maze 中循环。
