One of my colleague (Julien Danjou) wrote a book on advanced usage of Python. The book was out today and I strongly recommend buying it. Here is the summary of it:
Python is a wonderful programming language that is being used more and more in many different industries. It is fast, flexible, and it comes with batteries included.
Most of the books you read about Python will teach you the language basics – but once you’ve learnt them, you’re on your own in designing your application and discovering best practice.
In this book, we’ll see how you can leverage Python to efficiently tackle your problems and build great Python applications.
