updatedb.conf, Ignore files using pattern match/globbing

Running locate command with a file name returns multiple entries as, a.py a.pyc a.py~ Obviously, i am not looking for binaries/compiled files. I tried to configure locate command to ignore files that has pattern *.pyc, *.py~. Man page shows, locate command doesn't have globbing option. How can one configure locate command to ignore files that match a pattern?
