Creating a TCP/IP connection on already-networked computers

[John Salerno]

Let me see if this question even makes sense...I'm reading Core Python 
Programming and I jumped ahead to the more specific topics like network 
programming. I plan to follow along with the example in that chapter and 
create a socket connection between my desktop and laptop.

However, these two computers are already connected on my home network 
(using the Windows Network Setup Wizard), so I was wondering if this 
will have any effect on what I might try to do with Python. In other 
words, if the program I write actually works and allows the two 
computers to speak to each other, will that be a result purely of the 
program, or will it have anything to do with the fact that they are 
already on a home network together? (i.e. there's another variable in play?)

Thanks.
