3 Preface There s a famous old quote about writing maintainable software: Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. --John Woods comp.lang.c++ While I m not usually one for aphorisms, this one strikes a chord with me. Maybe it s because I ve spent my professional career writing software at huge companies, but I have yet to inherit code that didn t eventually cause me to curse the original author at some point. Everyone (besides you, of course, dear reader) struggles to write code that s easy to maintain. When Python became popular, many thought that, because of its terseness, it would naturally lead to more maintainable software. Alas, maintainability is not an emergent property of using an expressive language. Badly written Python code is just as unmaintainable as badly written C++, Perl, Java and all the rest of the languages known for their, ahem, readability. Terse code is not a free lunch. So what do we do? Resign ourselves to maintaining code we can t understand? Rant on Twitter and The Daily WTF about the awful code we have to work on? What must we do to stop the pain? Write. Idiomatic. Code. It s that simple. Idioms in a programming language are a sort of lingua franca to let future readers know exactly what we re trying to accomplish. We may document our code extensively, write exhaustive unit tests, and hold code reviews three times a day, but the fact remains: when someone else needs to make changes, the code is king. If that someone is you, all the documentation in the world won t help you understand unreadable code. After all, how can you even be sure the code is doing what the documentation says? We re usually reading someone else s code because there s a problem. But idiomatic code helps here, too. Even if it s wrong, when code is written idiomatiii

Introduction to Computation and Programming Using Python, Second Edition. This is the 'computational thinking' book we have all been waiting for!
You can do this before starting the class, or you can leave it until you've gotten far enough in the class that you want to write some code. The Google Python Class uses a simple, standard Python installation, although more complex strategies are possible. Python is free and open source, available for all operating systems from python.org. In particular we want a Python install where you can do two things: Run an existing python program, such as hello.py Run the Python interpreter interactively, so you can type code right at it Both of the above are done quite a lot in the lecture videos, and it's definitely something you need to be able to do to solve the exercises.
