1.staticmethod

类的静态方法，是类中使用staticmethod装饰的方法。可通过类本身或者类实例来调用，但是没有任何附加的隐式参数传递。方法内部调用类属性或者类方法的时候需要使用类的全名进行调用。

2. classmethod

使用 @classmethod 修饰器修饰的类型的方法，非私有的类方法可以通过类型本身或者类实例进行调用，并在调用时隐式传递类型本身作为第一个参数，该参数的形参名可以为任何合法变量名，但一般使用 cls。

3.相同点：

非私有类方法和类静态方法都可以通过类实例和类本身进行调用。
都可以通过继承被派生类拥有并重写。
都无法在方法内部调用类实例属性和类实例方法。

4.不同点：

类方法在调用时会隐式传递类型作为第一个参数；而类静态方法不会隐式传递任何值。
类方法的方法体中可以通过传递进来的类型实参调用该类型的类属性和类方法；而类静态方法内部不知道任何关于类型或者类实例的信息，** 但是可以通过类型本身的类型全名调用类属性和类方法。**

5.例子:

class Base(object):
    # 类属性
    ClassProperty = 0
    def __init__(self, first, second):
        # 类实例属性
        self.InstanceProperty = ""
        self.InstanceProperty1 = first
        self.instanceProperty2 = second
    def instance_method(self, msg):
        self.InstanceProperty = msg
        print self.__class__.__name__ + " instance_method" + self.InstanceProperty
    @classmethod
    def class_method(cls, msg):
        print cls.__name__ + " class_method" + msg
    @staticmethod
    def static_method(msg):
        print "static_method" + msg
    @classmethod
    def instance_factory_classmethod(cls, first):
        return cls(first, 100)
    @staticmethod
    def instance_factory_staticmethod(frist):
        return Base(frist, 200)
class DerivedA(Base):
    ClassProperty = ""
class DerivedB(Base):
    @classmethod
    def class_method(cls, msg):
        print cls.__name__ + " class_method" + msg
    @staticmethod
    def static_method(msg):
        print "Overrided static_method" + msg
if __name__ == "__main__":
    DerivedA(1, 2).instance_method(" called by instance")
    DerivedA(1, 2).class_method(" called by instance.")
    DerivedA.class_method(" called by Derived class itself.")
    DerivedA(1, 2).static_method(" called by instance.")
    DerivedA.static_method(" called by Derived class itself.")
    DerivedA.ClassProperty = "DerivedA.ClassProperty"
    print DerivedA.ClassProperty
    print '\n'
    DerivedB(1, 2).class_method(" called by instance.")
    DerivedB(1, 2).class_method(" called by instance.")
    DerivedB.class_method(" called by Derived class itself.")
    DerivedB(1, 2).static_method(" called by instance.")
    DerivedB.static_method(" called by Derived class itself.")
    print DerivedB.ClassProperty
    # 通过类静态方法获取类实例
    print isinstance(DerivedA.instance_factory_staticmethod(1), DerivedA)
    # 通过类方法后去类实例
    print isinstance(DerivedB.instance_factory_classmethod(1), DerivedB)

运行结果：

DerivedA instance_method called by instance
DerivedA class_method called by instance.
DerivedA class_method called by Derived class itself.
static_method called by instance.
static_method called by Derived class itself.
DerivedA.ClassProperty


DerivedB class_method called by instance.
DerivedB class_method called by instance.
DerivedB class_method called by Derived class itself.
Overrided static_method called by instance.
Overrided static_method called by Derived class itself.
