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
