# Sudkamp Languages And Machines - Python 3
All the algorithms from Sudkamp's [Languages and Machines](http://www.amazon.com/Languages-Machines-Introduction-Computer-Science/dp/0321322215) implemented in *Python 3*.
**Note:** If you prefer *Java*, the same work is being done in that language over in [thundergolfer/sudkamp-langs-machines-java](https://github.com/thundergolfer/sudkamp-langs-machines-java).
## Contributing
You are welcome to fork this repo in order to complete unimplemented algorithms or to improve on the existing ones. Please try to stick as close to the pseudo-code from the book.
