[DB-SIG] Probelm with inserting into postgres database using the pg module of python

[Mubaraka Arif]

please can someone send me a working code sample how they successfully 
used the pg module to insert one or more rows into an postgres database.

However , although I can query the database I have no success at 
inserting rows, except by hardcoding the values into the sql string.

I would appreciate yr help
