LMSPlayer errors when attempting to connect to player that is not conneced to server

[TristanStanton]

When attempting to use the LMSPlayer class directly with a MAC address that is not connected on the Logitech Media Server the following error occurs:

LMSTools/LMSTools/player.py", line 121, in parse_request
return self.request(command).get(key)
AttributeError: 'NoneType' object has no attribute 'get'

I have been able to resolve this by checking if the self.request(command) is None before attempting the attribute get(key):

    rcommand = self.request(command)
    if rcommand == None:
    	return None
    else:
     return rcommand.get(key)

However think this could be better resolved by checking if the player is present on the server during init

I'm not sure if doing it in __init__ is correct as the player could disconnect after the object has been initialised.

I think there just needs to be some error handling either returning None (as you suggest) or by raising some exception (e.g. ClientNotConnected) and having the user's code decide how to handle it.
