0318python list 深拷贝 和浅拷贝

list 的浅拷贝 碰到引用类型 只是复制个引用 ；深拷贝 使用import copy模块，

In [2]: lst0=[1,2,3,[234,23],4523,4,]

In [3]: import copy

In [4]: lst5=copy.deepcopy(lst0)

In [5]: lst5
Out[5]: [1, 2, 3, [234, 23], 4523, 4]

In [6]: lst5[3][1]=111

In [7]: lst5
Out[7]: [1, 2, 3, [234, 111], 4523, 4]

In [8]: lst0
Out[8]: [1, 2, 3, [234, 23], 4523, 4]

In [9]: lst5==lst0
Out[9]: False

In [10]: lst6=lst0

In [11]: lst6
Out[11]: [1, 2, 3, [234, 23], 4523, 4]

In [12]: lst6[3][1]=666

In [13]: lst6
Out[13]: [1, 2, 3, [234, 666], 4523, 4]

In [14]: lst0
Out[14]: [1, 2, 3, [234, 666], 4523, 4]
