Python 之 面向对象继承

基本继承语法

class f1:
    def f1(self):
        print('f1')

class f2(f1):
    def f2(self):
        print('f2')

class f3(f2):
    def f3(self):
        print('f3')

obj = f3()
obj.f1()
obj.f2()
obj.f3()

class f1:
    def f1(self):
        print('f1')

class f2(f1):
    def f2(self):
        print('f2')

class f3(f1):
    def f3(self):
        print('f3')

obj = f3()
obj.f1()
obj.f3()

obj1 = f2()
obj1.f1()
obj1.f2()

多继承

class f1:
    def f1(self):
        print('f1')

class f2():
    def f2(self):
        print('f2')

class f3(f1,f2):
    def f3(self):
        print('f3')

obj = f3()
obj.f1()
obj.f2()
obj.f3()
