Python code for the book *Artificial Intelligence: A Modern Approach.* We're loooking for one student sponsored by Google Summer of Code ([GSoC](https://summerofcode.withgoogle.com/)) to work on this project; if you want to be that student, make some good contributions here (by looking through the [Issues](https://github.com/aimacode/aima-python/issues) and resolving some), and submit an [application](https://summerofcode.withgoogle.com/terms/student). (However, be warned that we've had over 150 students express interest, so competition will be tough.) And we're always looking for solid contributors who are not affiliated with GSoC. A big thank you to everyone who has contributed!

Beyond the above rules, we use [Pep 8](https://www.python.org/dev/peps/pep-0008), with a few minor exceptions:

- You don't need two spaces after a sentence-ending period.

- Strunk and White is [not a good guide for English](http://chronicle.com/article/50-Years-of-Stupid-Grammar/25497).

- I prefer more concise docstrings; I don't follow [Pep 257](https://www.python.org/dev/peps/pep-0257/).
