# Other Code Conventions While we are mainly programming in C++, we do use other programming languages when appropriate. This chapter describes conventions for such code. ## Python Code written in Python should adhere to [PEP 8](https://www.python.org/dev/peps/pep-0008/). You should run `flake8` on your code to automatically check compliance. ## Common Lisp Code written in Common Lisp should adhere to [Google Common Lisp Style](https://google.github.io/styleguide/lispguide.xml).
