Hi All

Firstly i am new to pythong and I am stuck with the following problem
dont really know whether it has been posted previously in the mailing list(
pardon me if its so )

I have written (found in the net ) a small program to list the rpms in the
linux box

------------Starts here ------------
#!/usr/bin/python2.5
import rpm
ts=rpm.TransactionSet()
mi=ts.dbMatch()
for h in mi:
  print h['name']

--------Ends Here-----------------

It executes fine in the  python shell, but the problem is in when i execute
as a  python script  i get the following error
