python写rpc框架实用技巧

class TestClass(object):

    def __init__(self):
        super(TestClass, self).__init__()

    def __getattr__(self, item):

        def call(self, *args, **kwargs):
            info = {
                'called_name': item,
                'args': args
            }
            print info
        setattr(TestClass, item, call)
        return getattr(self, item)


a = TestClass()
a.cnmd('hello world')
a.nmbs(1, 2, 3, '4')

上面这种写法在用python写rpc框架的时候很实用, 谁用谁清楚
