I need help in making a desktop icon to execute a file

openSUSE 12.3
KDE 4.10.5

I have a Python file (script ?) that I want to be able to execute from my desktop.
It is an independent script that downloads activity from my credit card accounts.

While I was testing it, I would have to open Konsole, position myself in the proper directory and execute this:

Python Getupdate.py

How do I create an icon on my desktop that will do this ?

thanks
