#知识点:静态方法和动态方法
#静态方法属于类
#动态方法属于对象
 
class Province:
    memo = 'One of China\'s 23 provinces' #静态字段
     
    def __init__(self,name,capital,leadership):
        self.Name = name #动态字段
        self.Capital = capital #动态字段
        self.Leadership = leadership #动态字段
         
    def sports(self): #定义一个动态方法,类不能访问动态方法
        print self.Name + 'The sports meeting'
     
    #定义一个静态方法,实现类可以访问这个方法
    @staticmethod #第一步、加一个自带的装饰器
    def Foo(): #第二步,把shelf去掉
        print 'Anti-corruption activities'
 
#实例化两个对象,对象名分别是:hb、sd
hb = Province('hebei','shjiazhuang','liyang')
sd = Province('shandong','jinan','angshenghui')
 
#对象访问动态方法(注意:类不能访问动态方法)
hb.sports()
sd.sports()
 
#通过类名访问静态方法
Province.Foo()
 
#那么,对象是否能够访问静态方法呢?答案是可以的
hb.Foo()
