For anyone interested, I already moved the slides on github
(https://github.com/AndreaCrotti/pyconuk2012_slides)
and for example the decorator slides will be generated from this:

paragraph.

Is that a typo? I think you mean to make a recursive call to

for really big n powerlist3 always takes very much time :)
I would reiterate that a really big n is a really unusual use case for
a function like this, except

be sure that anything you demo interactively you include in your slide deck

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.
That is a v good suggestion.
the best presentation I ever attended was one on using an emergency

What do you think work best in general?
I find typing during class (other than small REPL examples) time consuming and
error prone.
What works well for me is to create a slidy HTML presentation with asciidoc,
then I can include code snippets that can be also run from the command line.
