super split!

gistfile1.py

import os

def super_split(absolute_path):
    fdir, fname = os.path.split(absolute_path)
    tokens = fname.split('.')
    ext = tokens[-1]
    fname_no_ext = '.'.join( [ x for x in tokens[:len(tokens)-1] ])
    return fdir, fname_no_ext, ext

(returning the favor)

check out os.path.splitext or

fname_no_ext, ext = fname.rsplit(".", 1)

@brentp thank you, sir. I've never used rsplit, and will have to add it to the lexicon.
