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

It’s probably because you have “ characters that are inside “ characters and it can’t tell where the string ends. It looks like you are trying to do

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

which doesn’t make sense.  Try using triple quotes instead so it’s clear what string you are trying to use.

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