Still trying to learn Python and was hoping some of you might be able to \
give me some advice  on my code 
below.  It works but I'm wondering if there's more efficient ways of doing \
this than the way  I've done it.

The first step is I have to loop thru nested folders and find all files \
that start with "LOGO".  So  I use Unix's 'find' 
and write all the paths out to a text file like so:

find ~/Desktop/logoFiles/ -type f -iname "LOGO*" > \
~/Desktop/logo_stuff/paths.txt"

Next, I use Python (code below) to look thru each paragraph of that file \
(paths.txt).  While  looping thru each 
paragraph, I want to first make sure that the folder name that the file is \
in is a number.  For  example, if it found 
file 'LOGO9012', then I'd want to make sure the folder name that this file \
was in was a  number (~/Desktop/
logoFiles/12/LOGO9012).  If that's ok then I grab the number off the file \
name.  If there's not  a number in the 
file name then I ignore it.  I then create a dictionary that has a key \
which equals the number I  grabbed from the 
file name and then the value contains the full file path (that I grabbed \
out of the text file)  followed by a 
delimiter (<::>) followed by 'LOGO' and the number I got from the file name \
(making sure to  keep any leading 
zeroes if they were there originally).  Finally, I sort the keys in \
numerical order and save out a  file with all the 
appropriate info from my dictionary (which will be a list of paths followed \
by a delimiter and  file name).  Here's 
an example of what this new file might contain:

/Users/jyoung1/Desktop/logoFiles/02/Logo002<::>LOGO002
/Users/jyoung1/Desktop/logoFiles/02/LOGO102<::>LOGO102
/Users/jyoung1/Desktop/logoFiles/02/LOGO302<::>LOGO302
/Users/jyoung1/Desktop/logoFiles/9/LOGO462.2PMS<::>LOGO462


Anyway, if anyone has time to look at this I'd appreciate your thoughts.  \
Thanks!

Jay
