python override筆記 其他特殊流程

這邊紀錄python繼承的其他特殊流程

父類別呼叫子類別的函數

In:

class Demo:
    def __demoprint(self):
        print('__demoprint')
    def demoprint_(self):
        print('demoprint_')
    def demo(self):
        print('demo')
        self.__demoprint()
        self.demoprint_()
class Demo1(Demo):
    def __init__(self):
        super().__init__()
    def __demoprint(self):
        print('__demo2print')
    def demoprint_(self):
        print('demo2print_')
    def demo1(self):
        print('demo1')
        super().demo()
d=Demo1()
d.demo1()

Out:

demo1
demo
__demoprint
demo2print_

再去call父類別function

In:

class Demo:
    def DemoF1(self):
        print("DemoF1")
    def DemoF2(self):
        self.DemoF1()
        print("DemoF2")
class Demo2(Demo):
    def DemoF1(self):
        print("Demo1F1")
        super().DemoF1()
    def Demo2F1(self):
        print('Demo2F1')
        super().DemoF2()
d = Demo2()
d.Demo2F1()

Out:

Demo2F1
Demo1F1
DemoF1
DemoF2
