想学习下Mixin技术，不过看到个基本的例子都报错，实在是没办法高手指定下吧，多谢！
main.py:
-------------------------------------------------
import Mixin
import mPrint
class A(Mixin.Mixin):
__mixinname__ = 'a'
def __init__(self):
self.initmixin()
self.callplugin('init', self)
if __name__ == '__main__':
a = A()
a.Print()
---------------------------------------
mPrint.py
-------------------------------------
#! /usr/bin/env python
#coding=utf-8
import Mixin
def init(self):
self.name = 'mPrint.py'
Mixin.setPlugin('a', 'init', init)
def Print(self):
print self.name
Mixin.setMixin('a', 'Print', Print)
报错信息如下：
