Python 继承 // 多继承

Posted 2020-10-13 hotfeng

import random as r
class Fish:
    def __init__(self):
        self.x = r.randint(0, 10)
        self.y = r.randint(0, 10)

    def move(self):
        self.x -= 1
        print(‘my pos is : ‘, self.x, self.y)

class Goldfish(Fish):
    pass

class Carp(Fish):
    pass

class Salmon(Fish):
    pass

class Shark(Fish):
    def __init__(self): # 重写父类__init__()方法
        Fish.__init__(self) # 继承方法1，需要指定父类名字
        super().__init__()  # 继承方法2，不需要指定父类名字，会自动查找
        self.hungry = True

    def eat(self):
        if self.hungry:
            print(‘eat everyday!‘)
            self.hungry = False
        else:
            print("I can‘t eat anymore!")

Python继承的两种方法：

　　1、className.funcName(args...)

　　2、super().funcName()

 

 1 class Base1:
 2     def func1(self):
 3         print("func1")
 4 
 5 class Base2:
 6     def func2(self):
 7         print("func2")
 8 
 9 class C(Base1, Base2): #多重继承
10     pass

多重继承直接在类名参数中添加要继承的类名即可
