Python client for lightstreamer

[epep]

Replacing the "raise IOError()" in the _handle_stream method is not a good idea, because a server error response while connecting is a symptom that something is not working properly, as you can read from Paragraph 4.1 of the Network Protocol Tutorial

In fact the only error I encountered for now with IG's stream server happen here, about 3 times a day, while trying to bind. I receive a SYNC ERROR about half a second after a LOOP message, before the binding is done. In this situation the reconnection work at first try.

I understand that errors in this point should be used with care for a clean client, but for my project I believe that the only errors that can occur here are the temporary ones, which would be resolved with a later reconnection.

It is necessary to remove the following line:self._stream_connection = None before invoking reconnect(), otherwise you'll run against a runtime error: it is a bug that I'm going to fix in our example

Thanks a lot ! I see the point : None has no close() method.

This line is also worthless before calling the bind() method ?
