I gave a 3-hour tutorial on Lambda Calculus at PyCon 2019. Here is a link to the screencast:

Here is a link to the official conference video:

Why this topic of all possible things to talk about? That’s a somewhat involved story, but I’m always interested in learning about new things that I just don’t know about. A few years back I started teaching the SICP course. Many of the of the examples from SICP are inspired by the lambda calculus so I thought it might be interesting to go off on a side-excursion to dig into a bit more. It turned out to be a lot more weird, fun, and interesting than I ever imagined. So, naturally it seemed to be a perfect tutorial topic to submit to PyCon–never mind the fact that it has almost nothing to do with Python.

Anyways, have fun watching. I welcome any feedback here.
