I don't like decorators, I think they're not worth the mental effort. So if I were to intend to your presentation, I'd really like you to start demonstrating how decorators are life savers, or with less emphasis, how they can be worth the effort and make me regret all these years without decorators. Some features in python have this WoW! effect, try to trigger it in front of your audience, that should really help them focus on the subject and be interested in your presentation. Also try to keep the presentation interactive by asking questions to your audience (unless some of them are already participating), otherwise people will be snoring or texting after 20 minutes. I think the key for a presentation is to make people interested in the subject and make them realize they can benefit from what you're presenting. Everyone can then google 'python decorators' for the technical and boring details. I must add that I'm not en experienced presenter, so take my advices for what they're worth (hmm not sure about this grammatical construct :-/ ) JM -- http://mail.python.org/mailman/listinfo/python-list
