浅拷贝和深拷贝的区别？
深拷贝无论有多少嵌套都会复制出来
例如：
import copy
# 题目
list01 = [44, 55, 66]
list02 = [11, 22, 33, list01]
list03 = list02 # 直接赋值
list04 = list02.copy() # 浅拷贝-copy
list05 = copy.copy(list02) # 浅拷贝 - copy
list06 = copy.deepcopy(list02) # 深拷贝 - deepcopy
# 修改List01
list01[0] = 88
list02[0] = 99
print(list01)
print(list02)
print(list03)
print(list04)
print(list05)
print(list06)
执行结果：
C:\python\python.exe C:/python/demo/file3.py
[88, 55, 66]
[99, 22, 33, [88, 55, 66]]
[99, 22, 33, [88, 55, 66]]
[11, 22, 33, [88, 55, 66]]
[11, 22, 33, [88, 55, 66]]
[11, 22, 33, [44, 55, 66]]
Process finished with exit code 0
