[Tutor] Trouble with os.path.isfile

[Carroll, Barry]

Carlos:

Thank you for your response.  

It turns out that Python and os.path.isfile() are working as expected.
A permissions conflict on my Linux-based system caused the isfile
function to return false for all the entries in the directory.  The web
server is running as user apache.  The files were owned by user iip.  I
don't have all the details worked out yet, but it appears that adding
apache to iip's group list resolves the conflict.  

It would be nice if the library entries for os.path.is* (where * is one
of {file, dir, link, mount) mentioned this restriction.

Regards,
 
Barry
