@staticmethod和@classmethod

# coding:utf-8
class A(object):
    bar = 1
    def foo(self):
        print 'hello i am foo'
    def myfoo(self):
        print 'hello i am myfoo'

    @staticmethod
    def static_foo():
        print 'static_foo'
        print A.bar

    @classmethod
    def class_foo(aabbcc):
        print 'class_foo'
        print aabbcc.bar
        aabbcc().foo()

A.static_foo()
A.class_foo()
print "~~~~~~~~~~"
a = A()
a.foo()
a.myfoo()

static_foo
1
class_foo
1
hello i am foo
~~~~~~~~~~
hello i am foo
hello i am myfoo

参考

使用@staticmethod或@classmethod，就可以不需要实例化，直接类名.方法名()来调用。
