Python程式設計：abc子產品實作抽象類

代碼示例

# -*- coding: utf-8 -*-

import abc


class Animal(abc.ABC):
    """動物類 抽象類"""

    @abc.abstractmethod
    def eat(self):
        """吃飯飯"""

    @abc.abstractmethod

        """睡覺覺"""


class Dog(Animal):
    """狗狗類 實作類"""

    def sleep(self):
        print("狗狗睡覺啦")

    def eat(self):
