Pythonic way to refer to files, paths, and full file paths?

Looking for a clear way to name my variables. Below is an example of the values they will store.

'IMG_5123.JPG'
'/path/to/IMG_5123.JPG'
'/path/to/'
 'JPG'

I was thinking filename, filename_full, path, extension. Is there a "proper" way to name these items?

In Unix and Unix-like operating systems you have the dirname and basename commands. If you use their widely used nomenclature then:

file basename: 'IMG_5123.JPG'
file name:     '/path/to/IMG_5123.JPG'
file dirname:  '/path/to/'
file suffix:   'JPG'

But nothing is ever that neat. The basename is also called the filename; the name is also called the full pathname; the dirname is often called the path, and the suffix is often called the extension.

This is just my perspective and you can of course select any scheme that you want.

Because they all represent parts of the same filename, I would prefix them all with "filename" or "fn" (if it's really clear what it means). Therefore: filename, filename_abs, filename_path, filename_ext or a similar set.

If they are going to represent images specifically I would probably modify that.

Your variables look ok to me. If you need additional inspiration you can check the std lib ofr os.path that's dealing with a lot of these concepts: http://docs.python.org/library/os.path.html
