SocketServer.py错误

Question

有人能看到这里的问题所在吗？我是python的新手，需要一些指导。我在装有Lion的mac上以32位模式运行Python 2.7.3。依赖项包括

pyOSC pyserial 2.6 python-xbee-api 2.00 optparse_gui 0.2 wxPython 2.8

如果有任何帮助，我将不胜感激！

当您使用不在字典中的键进行字典查找时，最常见的是引发KeyError异常。在本例中，它看起来应该在最后一行上：

self.hive.bees[ nid ].send_output( self.hive.serial, data )

..specifically，self.hive.bees[ nid ]部件。nid显然包含一个0值，而您的self.hive.bees字典中没有0键。
