Python面向对象编程 绑定方法

Posted 2020-10-21 bacardi

类的函数属性绑定给不同对象，是不同的绑定方法。对象调用绑定方法时会把对象本身当做self参数传入

示例代码

class People:
    country = ‘China‘
?
    def __init__(self, name, sex, age):
        self.Name = name
        self.Sex = sex
        self.Age = age
?
    def test(self):
        print(self)
?
?
conan = People(‘Conan‘, ‘male‘, 8)
wukong = People(‘wukong‘, ‘male‘, 18)
?
wukong.test()  # People.test(wukong)
conan.test()   # People.test(conan)
?
print(People.test,People.test(123))
print(wukong.test,wukong.test())
print(conan.test,wukong.test())

打印结果：

# <__main__.People object at 0x10813a320>
# <__main__.People object at 0x10813a2e8>
# <function People.test at 0x1081291e0>
# <bound method People.test of <__main__.People object at 0x10813a320>>
# <bound method People.test of <__main__.People object at 0x10813a2e8>>
