Before you use connect(), use 

socket.bind((ipaddr, port))

to determine the source addr and source port. If addr or port is equal to '' or 0, it means using OS default.

Just set the host IP like @Jalo said connect(('179.XX.XX.XX', 5005)), the system will choose wich interface needs to use to interact with that host.

If you need more info to understand how just read Routing in Linux
