"""Generic (shallow and deep) copying operations. Interface summary: import copy x = copy.copy(y) # make a shallow copy of y x = copy.deepcopy(y) # make a deep copy of y 使用案例 第一个是浅拷贝，第二个是深拷贝。 For module specific errors, copy.Error is raised. 本模块使用到的特殊的异常，copy.Error The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances). 深浅拷贝不同在于对容器类型的数据进行拷贝，容器类型有比如lists或者是class。 - A shallow copy constructs a new compound object and then (to the extent possible) inserts *the same objects* into it that the original
