The goal is to learn Drupal in a short time.
I am a programmer, proficient in Python/Django, PHP/CakePHP, Beatrix. I love Python, but at work so have to use PHP. At the moment I make websites on Bitrix, but given the number of shortcomings to look into Drupal.
Advise me what to read first, second etc. What books, documentation, tutorials, screencasts, and so on?
