美国VPS在python中使用hook函数，具体方法如下：



importtime



classLazyPerson(object):



def__init__(self,name):



self.name=name



self.watch_tv_func=None



self.have_dinner_func=None



defget_up(self):



print("%sgetupat:%s"%(self.name,time.time()))



defgo_to_sleep(self):



print("%sgotosleepat:%s"%(self.name,time.time()))



defregister_tv_hook(self,watch_tv_func):



self.watch_tv_func=watch_tv_func



defregister_dinner_hook(self,have_dinner_func):



self.have_dinner_func=have_dinner_func



defenjoy_a_lazy_day(self):



self.get_up()



time.sleep(3)



ifself.watch_tv_funcisnotNone:



self.watch_tv_func(self.name)



else:



print("notvtowatch")



time.sleep(3)



ifself.have_dinner_funcisnotNone:



self.have_dinner_func(self.name)



else:



print("nothingtoeatatdinner")



time.sleep(3)



self.go_to_sleep()



defwatch_daydayup(name):



print("%s:Theprogram---daydayup---isfunny!!!"%name)



defwatch_happyfamily(name):



print("%s:Theprogram---happyfamily---isboring!!!"%name)



defeat_meat(name):



print("%s:Themeatisnice!!!"%name)



defeat_hamburger(name):



print("%s:Thehamburgerisnotsobad!!!"%name)



if__name__=="__main__":



lazy_tom=LazyPerson("Tom")



lazy_jerry=LazyPerson("Jerry")



lazy_tom.register_tv_hook(watch_daydayup)



lazy_tom.register_dinner_hook(eat_meat)



lazy_jerry.register_tv_hook(watch_happyfamily)



lazy_jerry.register_dinner_hook(eat_hamburger)



lazy_tom.enjoy_a_lazy_day()



lazy_jerry.enjoy_a_lazy_day()
