[Tutor] fnmatch -or glob question

[Damon Timm]

Hi Kent and Allen - thanks for the responses ... I was sure there was
some part of the "search" I wasn't getting, but with your follow-up
questions it seemed something else was amiss ...

So, I went back to re-create the problem with some more python output
to show you and realized my mistake.  Sigh.  All the files were
DSC_00XX ... and then one I had chosen to test didn't have any
thumbnails.  So, of course, I wasn't getting any responses ... though,
because the filenames were so close, I sure thought I should have
been.

Good lesson here is: check the variables !

My goal is to delete the main image plus its thumbnails in one fell
swoop -- I plan to use fnmatch to do that (though glob works too).
Unless there is something else I should consider?

For those who stumble like me, here is what is working.

Python 2.5.2 (r252:60911, Jul 31 2008, 17:31:22)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from kissfist.read.models import Issue #custom model that stores issue info
>>> import os, fnmatch, glob
>>> i = Issue.objects.get(pk=1) # get the first issue (contains cover path)
>>> i.cover.path
'/media/uploads/issue-covers/DSC_0065.jpg'
>>> working_dir, file_name = os.path.split(i.cover.path)
>>> file_base, file_ext = os.path.splitext(file_name)
>>> glob_text = file_base + "*" + file_ext
>>> for f in os.listdir(working_dir):
...   if fnmatch.fnmatch(f, glob_text):
...     print f
...
DSC_0065.400x400.jpg
DSC_0065.jpg
DSC_0065.300.jpg
>>> os.chdir(working_dir)
>>> glob.glob(glob_text)
['DSC_0065.400x400.jpg', 'DSC_0065.jpg', 'DSC_0065.300.jpg']

Thanks again.

Damon
