If you agree with Dave, and you’re new to Python, I recommend focusing on the first chapter of Python Essential Reference. It’s the best 10-page overview of a programming language I’ve ever come across, and refer back to those pages often. I’ve written numerous scripts and have grown to really like Python over the years (it’s big inside Google), and this book has been indispensable.
