There are a few approaches you can take.  One is to using the
'glob.glob()' function, which lets you get a directory list that searches
based on a wildcard.  For example:

###
from glob import glob
print glob('./*.jpg')
###

will print us a list of all jpeg files in the current directory.  The
documentation talks about glob.glob (that's fun to say!  *grin*) here:

    http://python.org/doc/current/lib/module-glob.html


glob.glob() itself internally uses os.listdir(), filtering the results out
behind the scenes.  You might want to do the filtering yourself, but
glob.glob() should work pretty well for you.


Good luck!
