wolfkin@freedomspace.net already mentioned using string.find() to search
for substrings. Another alternative to string searching is to use the
glob() function within the 'glob' module, which will grab the filenames of
all .mp3 files for you. For example:
###
>>> from glob import glob
>>> glob('*.tex')
['foo.tex', 'abstractalgebra.tex']
###
The 'glob' module is documented here:
