 You can run the code in an IDE, or from the command line with `python -i filename.py` where the `-i` option puts you in an interactive loop where you can run Python functions. All notebooks are available in a [binder environment](http://mybinder.org/repo/aimacode/aima-python). Alternatively, visit [jupyter.org](http://jupyter.org/) for instructions on setting up your own Jupyter notebook environment.
 
 There is a sibling [aima-docker](https://github.com/rajatjain1997/aima-docker) project that shows you how to use docker containers to run more complex problems in more complex software environments.
