本文通过Python代码示例介绍了浅拷贝与深拷贝的区别，主要针对复合对象如列表和类实例等。此外，还展示了如何使用Python的copy模块创建新的类实例。

The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances).

import copy

class MyKlass(object):
    def __init__(self,name):
        self.name = name
    def test(self):
        print "this is " + self.name

class MyDict(dict):
    pass

def myFunction():
    print "this is function"


if __name__ == '__main__':
    k = type(MyKlass)
    print k    
    NewClass = copy.copy(MyKlass)
    NewClass("Python").test()
    d = type(MyDict)
    print d.__base__
    f = type(myFunction)
    print f.__name__
