Did you try to search on the error string? That would have gotten you the
solution (even) faster.
The first two Google hits (and probably all the rest of them), tell me that
Python 3's socket.send() method wants bytes as input, not str. See
http://docs.python.org/py3k/library/socket.html#socket.socket.send
Hope that helps,
