Python refresher & resources

Twelve short notebooks, readable in the browser — from calculator to pandas.

Office hours

When
Fridays, from 13:00 — by appointment only Email the teaching assistant with what you want to discuss and you will be given a slot. Turning up without one does not work.
Come with
A specific question, and what you already tried Bring project questions early — at the proposal stage, changing direction is cheap.
Not what this is for
Technical support, or having your code written We do not fix laptops, install software, or debug on your behalf, and we do not repeat a session you missed. The workspace removes the need for local setup; every week's materials are on this site.

Python refresher

These are static pages: the code is shown with the output it produced, but nothing runs in your browser and you cannot edit it here. To run and change them, open your Nuvolos workspace, where the same notebooks are ready to run — or download the notebook and open it wherever you work.
