__init__()

Posted 2021-02-03 pzk7788

__init__() 是类的内置方法，用于初始化类的内部状态，当我们去实例化一个对象的时候，默认就会执行 __init__() 下面的语句，例子如下：

#!/usr/bin/env python
#-*- coding:utf-8 -*-

class People(object):
    def __init__(self): 
        self.name = ‘Tom‘
        self.age = 23
        self.talk()

    def talk(self):
        print(‘My name is %s‘ % self.name)
        print(‘My age is %s‘ % self.age)

if __name__ == ‘__main__‘:
    obj = People()

[[email protected] ~]$ python 1.py 
My name is Tom
My age is 23
