Hallo. I just want to make a small program written in python and Gtk (Pygtk). I have installed gtk2.0 and now pygtk through apt-get install python-gtk2 and apt-get install python-gtk2-dev, but everytime that I want to run the script made in pygtk it doesn't run and the Kate editor opens the file. maybe I have installed the false files. Could somebody tell me what's the problem?. Thanks.
