I am beginner at using python language.
I mean i am implementing that in a  windows based machine and wanted
to transfer files over the LAN. I have written down two files as
client.py and server.py . I ran these files at two different Computers
in the LAN and  I was able to send small chunks of messages( like
chat).

I was successful in establishing connection and sending small
messages. But now i want to transfer a complete file with out using
the ftplib(FTP LIBRARY) in python.


The files look like this.i hope this would help.
