in reply to Perl tutorial building on Python skills?
It might require some unlearning or deprogramming. I've had success in the past with someone experienced in another language, and just going through with them in a manner that has them come up with a programming task (or idiom.) in the their strong language; then showing them the Perl idiom. General concepts about dynamic languages in your case sounds like it should not be a barrier. This relies on them being proficient with another language (here Python); and the stronger the better.
Another thing that comes to mind that might be helpful is, Rosetta Code.
