模板代碼：

class People:'所有員工的基類'#構(gòu)造函數(shù)def __init__(self, user_id, user_name):self.user_id = user_idself.user_name = user_name#析構(gòu)函數(shù)def __del__(self):class_name = self.__class__.__name__print(class_name, '銷毀')def get_info(self):print("people: ", "name = ," + self.user_name, "id = ", self.user_id)def __str__(self):return "people\n user_id: %d \t user_name: %s "%(self.user_id, self.user_name)

測(cè)試代碼：

from People import People p1 = People(1, 'alan') p2 = People(2, 'dream') p3 = People(3, 'zuora') people_list = [p1, p2, p3] for people in people_list:print(people) # setattr(p1, 'age', '23') #對(duì)當(dāng)個(gè)對(duì)象添加屬性 # print("setattr: ", p1.age) #對(duì)當(dāng)個(gè)對(duì)象刪除屬性 # delattr(p1, 'age') #返回屬性值 # getattr(p1, 'age') #判斷屬性值是否存在 # hasattr(p1, 'age')

輸出：

peopleuser_id: 1 user_name: alan peopleuser_id: 2 user_name: dream peopleuser_id: 3 user_name: zuora People 銷毀 People 銷毀 People 銷毀
