python getattr函数的妙用

import platform

class Test:
    def test(self):
        func = getattr(self,'windows')
        func()

    @staticmethod
    def windows():
        from plugins.collect_windows_info import Win32Info
        return Win32Info().collect() #在调用self对象时，本类调用用Win32Info().collect()
    @staticmethod
    def linux():
        return 'OK2'





if __name__ == '__main__':
    ob  = Test()
    ob.test()
    print(ob.windows())
