Throwback Thursday inspired code.
For anyone else out there finding this, if you take the code and modify it or put it somewhere else public,
let me know. If I do such a thing, I too will let you know.
First off, all I wanted was a way to find images for Throwback Thursday and I have a very messy folder called Pictures and in there my photos go back to 2003, November.
Some are older, but their modification/creation dates on my computer will not reflect their true date/time so this tool will be useless for those. Unless I modify it later, for example, I can think of an improvement. . . if date modified content does not match date in name of file (parse the name of the file) then use the name as the date.
[update] I am not sure how to make this better. It is definitely not 100% accurate. For example, today, some of the 10 images I've pulled up were created on 9/6/2012 (Thursday) BUT they were created for a web-site by a script I used in the past. By pure coincidence, it also happens to be originally taken on Thursday, July 19, 2012... so, here it is :).

The code is currently below. I also put it on
Siafoo.
================================= usage:
Mac OS X Terminal with python3 and python installed. This python3 is 3.4.
Show in Mac Preview app 10 files of png or jpg found in /foo/bar directory:
python3 tbt.py /foo/bar/ -n 10 -m
List all files in /foo/bar directory:
python3 tbt.py -l /foo/bar
List all options with -h:
unknown68a86d404130:play michaelcase$ python3 tbt.py -h
usage: tbt.py [-h] [-d D] [-l] [-m] [-mw] [-n N] directory
Program for "Throwback Thursdays" allows users to specify day of week to find,
defaults to Thursday, and provides a list of files of jpg and png within the directory you
specify that occurred on that day of week. However, precedence goes mw, m then
l. In other words, ONLY ONE of those flags will be supported, if you specify
more than one, the precedence is enforced.
positional arguments:
directory Required. Directory from which to read files.
optional arguments:
-h, --help show this help message and exit
-d D Optional. Day of week. Defaults to Thursday. Can not do multiple
days.
-l Optional. Reply with list of files that can be passed to
something like xargs.
-m Optional. Mac OS open Preview App with resulting list of files.
If the list of files gets too long, the command may fail.
-mw Optional. Mac OS open Preview App with one image per window. Can
be torture to your screen, be careful.
-n N Optional. Number of files to *randomly* retreive from list.

================================= code, cut here to end. put in file tyt.py
# use os.path.getctime to get creation date/time.
# use date.weekday() to get 0 = Monday to 6 = Sunday.
# then use present Thursdays as tbt files :)
# ctime - the last time the file's inode was changed (e.g. permissions changed, file renamed, etc..)
# mtime - last time the file's CONTENTS were changed
# atime - last time the file was accessed.
