python -- 类中self到底有什么用？再续

a = 1


def say():
    print('调用了全局方法(people外)')

    
class Creative_1(object):
    
  
    def say(self):
        print('来自Creative_1的say')
    

class Creative(object):
    c=100
    def say(self):
        print('来自Creative的say')

    def creative_say(self):
        self.say()
        


class People(Creative_1,Creative):

    a = 100
    b = 123

    def __init__(self):
        self.a = 10000

    @classmethod
    def talk(cls):
        print('这里是people类方法')



    def say(self):
        print('调用了People类里面的方法')

    # def say():
    #     print('来自无需self的say函数')

    @staticmethod
    def tool():
        print('来自People类的工具包')



    def do(self):
        say()
        super().say() 
        self.say()
        Creative.say(self)
        print('a = ', a)
        print('self.a = ', self.a)
        print('self.b = ', self.b)
        print('self.c = ', self.c)
        print('People.b = ', People.b)


p = People()
p.do()
p.creative_say()

揭晓答案

调用了全局方法(people外)
来自Creative_1的say
调用了People类里面的方法
来自Creative的say
a =  1
self.a =  10000
self.b =  123
self.c =  100
People.b =  123
调用了People类里面的方法
