Maybe, but I think the book really was different from any book I had read before. Most books teach the language, but Think Python showed me some of the why, what each data structure might be used for, it would quickly dip into some interesting implementation details to give me a more solid foundation and then zoom out and give me perspective on why something is useful and related software writing skills and tips. It was thorough, but also concise, and the exercises were engaging, so I found myself for the first time really getting sucked into the zone with the problems and time was flying by. This hadn’t happened to me with Java or Perl.
