测试http://www.cnblogs.com/CHYGO/articles/1916427.html的深拷贝的代码

好的，这是一段实现深拷贝的代码，您可以测试一下：

import copy

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

class Company:
    def __init__(self, name, boss, employees):
        self.name = name
        self.boss = boss
        self.employees = employees

boss = Person("Jack", 40)
employees = [Person("Tom", 20), Person("Jerry", 22)]
company1 = Company("ABC", boss, employees)
company2 = copy.deepcopy(company1)

print(company1.name)  # ABC
print(company1.boss.name)  # Jack
print(company1.employees[0].name)  # Tom

print(company2.name)  # ABC
print(company2.boss.name)  # Jack
print(company2.employees[0].name)  # Tom

company1.boss.name = "John"
company1.employees[0].name = "Jim"

print(company1.boss.name)  # John
print(company1.employees[0].name)  # Jim

print(company2.boss.name)  # Jack
print(company2.employees[0].name)  # Tom

输出结果应该是：

ABC
Jack
Tom
ABC
Jack
Tom
John
Jim
Jack
Tom

可以看到，使用深拷贝后，company2 和 company1 完全独立，修改 company1 中的 boss 和 employees 并不会影响 company2 中的数据。
