Python Class （一）

继承

class Character(object):
    def __init__(self, name):
        self.health = 100
        self.name = name
    def printName(self):
        print (self.name)

class Blacksmith(Character):
    def __init__(self, name, forgeName):
        super(Blacksmith, self).__init__(name)
        self.forge = Forge(forgeName)

class Forge:
    def  __init__(self, forgeName):
        self.name = forgeName

bs = Blacksmith("Andy", "Dufresne")
bs.printName()
print (bs.forge.name)

覆盖

class BaseClass(object):
    def test(self):
        print ("ham")

class InClass(BaseClass):
    def test(self):
        print ("hammer time")

i = InClass()
i.test()

可以打印出子类：

print (BaseClass.__subclasses__())
[<class '__main__.InClass'>]
