    db=MySQLdb.Connect('host="localhost", user="%s", passwd="%s"' % x,y)
TypeError: not enough arguments for format string

You don’t need to use string interpolation ("%s" % ...) here.

import MySQLdb
user = raw_input('user> ')
password = raw_input('passwd> ')
db=MySQLdb.connect(host="localhost", user=user, passwd=password)
cursor=db.cursor()
cursor.execute('GRANT ALL ON squidctrl.* TO sams@localhost IDENTIFIED BY "connect";')
cursor.execute('GRANT ALL ON squidlog.* TO sams@localhost IDENTIFIED BY "connect";')
cursor.close()
