Python代码中的错误

-1

请参阅代码和最后一个错误。Python代码中的错误

from brisa.core.reactors import install_default_reactor 
reactor = install_default_reactor() 
print reactor 

import os 

from brisa.upnp.device import Device, Service 
from brisa.upnp.device.service import StateVariable 


class BinaryLight(Device): 

    def __init__(self): 
     Device.__init__(self, 
         'urn:schemas-upnp-org:device:BinaryLight:1', 
         'Binary Light device') 


class SwitchPower(Service): 

    def __init__(self): 
     Service.__init__(self, 
         'SwitchPower', 
         'urn:schemas-upnp-org:service:SwitchPower:1', 
         '', 
         os.getcwd() + '/SwitchPower-scpd.xml') 
     self.target = False 
     self.status = False 
     self.varin = StateVariable(self, "Status", 
           True, False, "boolean") 
     self.varin.subscribe_for_update(self.varUpdateCallback) 
     self.add_state_variable(self.varin) 

    def varUpdateCallback(self, name, value): 
     print name, 'was updated to', value 

    def SetTarget(self, *args, **kwargs): 
     self.target = kwargs['NewTargetValue'] 
     self.status = self.target 
     self.set_state_variable('Status', self.target) 
     print 'Light switched ', {'1': 'on', '0': 'off'}.get(self.target, None) 
     return {} 

    def GetTarget(self, *args, **kwargs): 
     return {'RetTargetValue': self.target} 

    def soap_GetStatus(self, *args, **kwargs): 
     return {'ResultStatus': self.status} 


if __name__ == '__main__': 
    device = BinaryLight() 
    device += SwitchPower() 

    # Start device 
    device.start() 

    # Setup main loop 
    reactor.add_after_stop_func(device.stop) 
    reactor.main()

我得到一个错误： -

ANKIT @ Ubuntu的：〜/桌面$蟒蛇binary_light.py能否请你告诉我，我做的错误？

Error:

是不是“错误”只是从`打印reactor`输出？ – 2011-02-05 01:27:13

是的...非常感谢....我看不到打印声明 – user1492832 2011-02-05 01:30:28

正如其他人所说，这不是一个错误。但是，我的猜测是，你有一个错误，并出现一些问题或者你不会在这里发帖。尝试删除打印语句。然后让我们知道你是否有更多的“错误”。

这不是一个错误。在第3行，您正在打印对象“reactor”。

（针对更新问题）

好了，错误提示无法找到网络。

看着the code，试图在你的脚本开始这样做：

import brisa 
brisa.__enable_offline_mode__ = True 
from brisa.core.reactors import install_default_reactor
