This notebook uses the commandline tools cowsay and lolcat, which were automatically installed because we included them in our apt.txt file.

The cell uses them in a system shell (note the exclamation mark) to fancify the Zen of Python.

  • Note: These tools were installed to /usr/games by the system's package manager and that directory is not in the path) by default. The postBuild file is used to add /usr/games to the path.
