I used this to move all my video files from one directory into their own subdirectories with the same name as the file.

filemove.py

import os
import shutil
import fnmatch

path = os.getcwd()
filelist = os.listdir(path)

files = fnmatch.filter(filelist, '*.avi')
# If you have more than one file type:
# files += fnmatch.filter(filelist, '*.m4v')
# files += fnmatch.filter(filelist, '*.mkv')


for name in filelist:
    os.mkdir(name[:-4])
    shutil.move(name,name[:-4])
