I don't know how to get Python to read more than teh nominal file size if it is

If you want to read the register value a second time, you need to seek to the
beginning of the file first, then read four bytes. You should be able to
repeat the seek/read pattern as many times as you want.
I close the file after I write to it and open it again for the read.
After I write to the file, "ls -l" gives a size of zero instead of 4.
If that's not what's confusing you, can you please clarify what is?
I am not trying to mix reads and writes on an open file. I know about
seek and tell if that were what I wanted to do.
