How does a spreadsheet work? A tour of the codebase of Dirigible, the Pythonic spreadsheet by Harry Percival

As always an entertaining speaker.  Harry gave us a world wind tour of the code related to a end of life, open source, project https://github.com/pythonanywhere/dirigible-spreadsheet

He also encouraged any self respecting Pythonista to sign up and register for an account at  www.pythonanywhere.com.

Tip: Did you know you could add a name space to eval commands, to limit their scope.
