First, the snippet provided is a contrived example of a much larger program.
http://pastebin.com/xRqBE5BY (written in python3 with access to 3.4 if necessary) The goal: To connect to a listening socket and send commands to the cmd.Cmd() loop running, then show the output to both stdout and the remote connection. Right now, I have a solution that will work as long as everything that needs to get sent to stdout and the socket is return'd from each function instead of printed. Because this is already a larger project, I would prefer not to have to go back through and refactor everything to facilitate the remote control (the actual program involves threading and locks etc etc). I feel like there should be a fairly simple solution dealing with duplicating the file descriptor or something similar. I've messed around trying to find something like that, but without success. I've also looked into the contextlib.redirect_stdout, but it expects a file type object. Also, using socket.makefile() results in the returned object not having a fileno() method, so I can't use select on it. Basically, I'm hoping someone here knows some file descriptor-fu or some other cleaner solution. Any help would be appreciated! remote display ------------- | ------------ menu display $>nc localhost 12345 | s function called. s | h function called. s function called. | Traceback ... h | 44: 'NoneType' object has no attribute 'strip' $> -- https://mail.python.org/mailman/listinfo/python-list
