Python mySQL Update, Working but not updating table

I have a python script which needs to update a mysql database, I have so far:

dbb = MySQLdb.connect(host="localhost", 
       user="user", 
       passwd="pass", 
       db="database") 
try:
   curb = dbb.cursor()
   curb.execute ("UPDATE RadioGroups SET CurrentState=1 WHERE RadioID=11")
   print "Row(s) were updated :" +  str(curb.rowcount)
   curb.close()
except MySQLdb.Error, e:
   print "query failed<br/>"
   print e  

The script prints Row(s) were updated : with the correct number of rows which have a RadioID of 11. If I change the RadioID to another number not present in the table it will say Row(s) were updated :0. However the database doesn't actually update. The CurrentState field just stays the same. If I copy and past the SQL statement in to PHPMyAdmin it works fine.

use

dbb.commit()

after

curb.execute ("UPDATE RadioGroups SET CurrentState=1 WHERE RadioID=11")

to commit all the changes that you 'loaded' into the mysql server
