每当我想制作新地板时，我都会调用它。我的房间是数组，r1 = [..] r2 = [..] 等。我尝试做的是复制其中一个数组并将其用作我的房间，这样我就不会更改原始数组。但是，当我到下一层，再次调用该函数并制作数组的副本时，它们与原始数组不同，而是与我第一次调用该函数时复制的数组相同。为什么是这样？
解决方案
在 python 中使用=永远不会复制任何东西。绝不。
要制作副本，最好使用copypython 中的模块。您可以在 python 中制作对象的浅拷贝和深拷贝。
deepcopy如果您list包含（引用）其他列表或其他对象，则应该使用。
>>> import copy
>>> l = [1, 2, 3]
>>> lc = copy.deepcopy(l)
>>> lc
[1, 2, 3]
>>> lc.append(4)
>>> l
[1, 2, 3]
>>> lc
[1, 2, 3, 4]
