Screencasts

Python Morsels currently includes 78 screencasts (each is about 3 minutes long). I publish one or two new screencasts each week. The most recently published screencasts are at the top of this page.

These screencasts are broken into topic trails in which each screencast builds on prior screencasts. I recommend watching earlier screencasts in each topic trail before later ones.

Don't like watching videos? That's okay! Every screencast includes a transcript. So you can think of these screencasts as mini blog posts!
