[Tutor] SyntaxError: can't assign to literal while using ""blkid -o export %s | grep 'TYPE' | cut -d"=" -f3" % (fs)" using subprocess module in Python

[srinivasan]

Some I managed to fix temporarily as below, might be useful for others.
Also please correct me if anything wrong or for any improvements in the
below

        cmd = "blkid -o export %s" % partition_path
        out = self._helper.execute_cmd_output_string(cmd)
        var = out.split("TYPE=", 1)[1]
        quoted = re.compile('(?<=^\")[^"]*')
        for string in quoted.findall(var):
            return string
