It should be possible to just execute

    sock.send(open("somefile").read())

if sock is a connected stream socket.  You might want to break it down in
chunks though, either to conserve local memory or provide transit feedback:

    f = open("somefile")
    while 1:
        data = f.read(8192)
        if not data:
            break
        sock.send(data)
        sys.stderr.write(".")
        sys.stderr.flush()
    sys.stderr.write("\n")
