Thanks Paul.
getcwd() tells me that my cwd is /home/debian/Desktop when I use f =
open('MyFile.txt', w). I am using Try/Except and not getting an
exception with the open() statement. Perhaps I can't write a text file
to the Desktop, but it seems like it should give me an error message.

Does this file already exist ? You should check the documentation
for the file write() method and see what all is required for the
method to work correctly. Also, as I said I'm no python developer,
but the code shown there is really bad form. There is no error
checking on the file object when attempting the open() call. In C
this would be done by checking the value of f, but I'm not even
sure this is possible in python.
So I'd attempt to help you trouble shoot this by writing code
myself, here, and testing. But I'm very "allergic" to python. Or
more correctly, I'm getting old, and set in my ways, and python
just is not in my future plans. *ever* . . .

This is done no different than it is done on any Linux system.
The point here is that you should go out and find any good
python tutorial, that covers writing to a file, and follow it.

I want to store a little data on the eMMC from my
Python code. My program is not getting errors when I
try to write a very short data file but it doesn't
actually seem to write it as I cannot read it back. I
am using
f = open('MyFile.txt', w)
or
f = open('/home/debian/Desktop/MyFile.txt', w)
or
f = open('MyFile.txt', r)
or
f = open('/home/debian/Desktop/MyFile.txt', r)
to open the file and am not getting any errors but
Python is not finding the file and I cannot find the
file with a search from WinSCP.
So how to create a data file and where does it go?
Thanks,
John
