modifying key's name in python dictionary

Question

I am trying to write a python script so that I can find all sub_directories called 'something' within a parent directory.Then I would like to rename the sub directories and move them somewhere else. So far I have my code as:

import os, shutil,fnmatch

match = {}
for root, dirnames, filenames in os.walk('test'):
    #print root
    #print dirnames
    #print filenames
    for i in fnmatch.filter(dirnames,'find'):
        #print os.path.join(root,dirnames[0])
        print root
        #match.append(root)
        match[root]=dirnames[0]

call match gives me something like {'test\a': 'find'......}. I would like to modify the key value of the dictionary so that it looks like {'a':'find'... so essentially I am trying to get rid of the name of the parent directory. I thought about converting to string and use split but seems to be not so efficient.

or better question, is there a way I can store the path name without including the first directory. I am only working with level two path (so something like test/a/find) — Pupusa, Jul 11 '15 at 04:47
I think `os.path.basename(dirname)` should do the trick for you... — Iron Fist, Jul 11 '15 at 04:48

To get the dirname without the parent directory name, use os.path.basename, this way:

>>> dirname = 'C:\\Users\\myUsers\\Videos'
>>> os.path.basename(dirname)
'Videos'

EDIT: in response to OP comments,

Given:

dirname = 'C:\\Users\\myUsers\\Videos'

And you want to get new folder name as myUsers_Videos, here is one way:

>>> os.path.basename('_'.join(os.path.split(dirname)))
'myUsers_Videos'

yea but I also need the folder above \vidoes for renaming purpose. – Pupusa Jul 11 '15 at 05:00
@xiaocheng Do you want it as `absolute` path or just name of folder? – Iron Fist Jul 11 '15 at 05:06
for instance the folder I want to find is called 'find' and its path is test/a/find, I want to rename the find folder as a_find and move it somewhere else. sorry for the confusion – Pupusa Jul 11 '15 at 05:09
so the new folder name will be a combination of both folders names, right? – Iron Fist Jul 11 '15 at 05:11

I was able to obtain what I want using copytree from shutil module. – Pupusa Jul 13 '15 at 18:51
