Even so, it's probably a good idea to avoid using 'from os import open',
as lots of folks probably expect open() to stand for the standard
"builtin" open function.


Sudhir, it does sounds like you're using something like 'from os import
*'.  The 'from' statement's meant to plunk the contents of a module
directly into the global namespace for convenience sake, but is
problematic since it plunks the contents of a module directly into the
global namespace.  *grin*

Doing something like 'from os import *' ends up overwriting some important
builtin functions like open() so that they're not easily accessible
anymore.  Can you check to see if you can find that 'from os import *' in
your code?

The Python Tutorial does have a section on 'Importing * From a a Package';
it might be useful for you:

Good luck!
