This is more appropriate for python-list than for python-dev, which is
about the development OF Python. But your problem here is quite
simple:

>         cmd = "blkid -o export %s | grep 'TYPE' | cut -d"=" -f3" % (fs)

You're trying to use the same quotation mark inside the string and
outside it. That's not going to work. Try removing your inner quotes.

You may also want to consider using Python to do your searching and
cutting, rather than a shell pipeline. For more information on that,
ask on python-list; people will be very happy to help out.
