Searching the values in a list for values of a list of mysql values

If it's not obvious from the code, I'm really new to Python, but I've some experience in JavaScript and PHP.  In my code I'm attempting to check the extensions of a list of files to see if they have a certain extension.  I know that I could use the glob module to create a list of only the files with the extensions, but I the extensions I'm looking for need to be taken from a mysql database.  This is a cgi script.  Anyways, when the extensions list is printed it prints like this:
(('aac',), ('aif',), ('ape',), ('flac',)
I'm getting an error message about my regular expression, which I'm not really sure about:
<class 'sre_constants.error'>: nothing to repeat
Can you point out the mistake in my logic and or syntax?
I'd also accept an alternative method that would achieve the same thing.
Thanks ahead of time.

Shouldn't that be:

if re.search(str(ext), fi):

Wow, that's really embarrassing.  I was looking right at the manual when I typed that.
Thanks!
