下面这些是什么意思：@classmethod, @staticmethod, @property？

@classmethod, @staticmethod和@property这三个装饰器的使用对象是在类中定义的函数。下面的例子展示了它们的用法和行为：

class MyClass(object):
    def __init__(self):
        self._some_property = "properties are nice"
        self._some_other_property = "VERY nice"
    def normal_method(*args,**kwargs):
        print "calling normal_method({0},{1})".format(args,kwargs)
    @classmethod
    def class_method(*args,**kwargs):
        print "calling class_method({0},{1})".format(args,kwargs)
    @staticmethod
    def static_method(*args,**kwargs):
        print "calling static_method({0},{1})".format(args,kwargs)
    @property
    def some_property(self,*args,**kwargs):
        print "calling some_property getter({0},{1},{2})".format(self,args,kwargs)
        return self._some_property
    @some_property.setter
    def some_property(self,*args,**kwargs):
        print "calling some_property setter({0},{1},{2})".format(self,args,kwargs)
        self._some_property = args[0]
    @property
    def some_other_property(self,*args,**kwargs):
        print "calling some_other_property getter({0},{1},{2})".format(self,args,kwargs)
        return self._some_other_property

o = MyClass()
# 未装饰的方法还是正常的行为方式，需要当前的类实例（self）作为第一个参数。

o.normal_method 
# <bound method MyClass.normal_method of <__main__.MyClass instance at 0x7fdd2537ea28>>

o.normal_method() 
# normal_method((<__main__.MyClass instance at 0x7fdd2537ea28>,),{})

o.normal_method(1,2,x=3,
