带有变量引用的Python列表

Question

我已将我的列表编号为layer1，layer2 ...我想在调用它时使用变量（playery）作为列表名称中的数字，因此如果playery等于4，则列出的列表将是layer4

layer1 = [".", ".", ".", ".", "."]
layer2 = [".", ".", ".", ".", "."]
layer3 = [".", ".", "■", ".", "."]
layer4 = [".", ".", ".", ".", "."]
layer5 = [".", ".", ".", ".", "."]
playerx = (3)
playery = (4)
(layer(playery - 1))[playerx-1]= (".")

(layer(playery))[playerx-1]= ("■")

这是我到目前为止所做的，但它不起作用

Answer 1

这是你应该做的。

layers = [[".", ".", ".", ".", "."],
          [".", ".", ".", ".", "."],
          [".", ".", "■", ".", "."],
          [".", ".", ".", ".", "."],
          [".", ".", ".", ".", "."]]

>> playerx = 3
>> playery = 4
>> layers[playery - 1][playerx - 1]= "."
>> layers[playery][playerx - 1]= "."

Answer 2

像这样创建2D数组：

layers= [layer1, layer2, layer3, layer4, layer5]

如果你想得到“■”你应该键入：

layers[2][2]
