面向对象编程之mixins机制及super方法

class Father:  # 真正的父类，有三个子类共用功能
    def commmon_func(self):
        pass
class FuncMixin:  # 其中两个个子类特有的功能，类名用Mixin结尾，读代码时一眼可明意，此为混入的功能，并非父类
    def special_func(self):
        pass
class Son_1(FuncMixin, Father):
    pass
class Son_2(FuncMixin, Father):
    pass
class Son_3(Father):
    pass

class Father:
    def __init__(self, name, age, gender):
        self.name = name
        self.age = age
        self.gender = gender
    def func(self):
        print(self.name)
        print(self.age)
        print(self.gender)
class Son(Father):
    def __init__(self, name, age, gender, job):
        Father.__init__(self, name, age, gender)
        self.job = job
    def func(self):
        Father.func(self)  # 用类调用功能，不会自动传参，需要填入 self
        print(self.job)

class Father:
    def __init__(self, name, age, gender):
        self.name = name
        self.age = age
        self.gender = gender
    def func(self):
        print(self.name)
        print(self.age)
        print(self.gender)
class Son(Father):
    def __init__(self, name, age, gender, job):
        super().__init__(name, age, gender)
        self.job = job
    def func(self):
        super().func()  # 使用 super方法，会自动传入 self
        print(self.job)
