Start programming, learn Python

Recently I've been asked to send a few links to absolute beginners who want to start programming. As a language choice, I always recommend to start with Python. So I ended up to collect a list useful links for Python beginners:


Tutorials

• Learn python the hard way by Zed Shaw - (mostly recommended) http://learnpythonthehardway.org/
