# 类属性的增删改查 import time class Chinesepeople: country = 'China' person_type = '人' def __init__(self, name): self.name = name def play_ball(self, ball): print('%s正在玩%s' % (self.name, ball)) def eat_foot(self, foot): print('%s正在吃%s' % (self.name, foot)) # 查看类属性 print(Chinesepeople.country) # 修改类属性 Chinesepeople.country = 'CHINA' print(Chinesepeople.country) # 增加类属性 Chinesepeople.time_now = time.asctime() # 删除类属性 print(Chinesepeople.__dict__) del Chinesepeople.person_type print(Chinesepeople.__dict__) person1 = Chinesepeople('jack') person1.play_ball(ball='ball') print(person1.time_now)
# 实例属性的增删改查 class Chinese: def __init__(self, name): self.name = name def play_ball(self, ball): print('%s正在完%s' % (self.name, ball)) person1 = Chinese('alex') # 查看 print(person1.name) # 增加 person1.age = 18 print(person1.age) # 修改 person1.age = 20 print(person1.age) print(person1.__dict__) # 删除 del person1.age print(person1.__dict__)
