A few months ago in September, I attended my very first PyBay: an annual conference in San Francisco bringing together Pythonistas from across the bay area. It was a 2-track single-day conference, with nearly 300 attendees, and talks ranging from 10 to 60 minutes.
My talk
I was very honored to present one of the first talks of the day, on a topic that's near and dear to my heart: improv! Back before I had kids, I spent many years taking improv classes and running an improv club with friends out of my home. I love that improv games force me to be in the moment, and I also just generally find spontaneous generation to be a source of much hilarity. 😜
I've always wanted an excuse to re-create my favorite improv games as computer programs, and now with language models (both small and large), it's actually quite doable! So my talk was about "Playing improv with Python", where I used local models (Llama 3.1 and Phi 3.5) to play increasingly complex games, and demonstrated different approaches along the way: prompt engineering, few-shot examples, function callings, and multimodal input. You can check out my slides and code examples. You're always welcome to re-use my slides or examples yourself!- I spoke with several folks who want to use them as a way to teach language models.
To make the talk more interactive, I also asked the audience to play improv games, starting with a audience-wide game of "reverse charades", where attendees acted out a word displayed on the screen while a kind volunteer attempted to guess the word. I was very nervous about asking the audience for such a high level of interactivity, and thrilled when they joined in! Here's a shot from one part of the room:
Then, before each talk, I asked for volunteers to come on stage to play each of the games, before making the computer play them. Once again, the attendees eagerly jumped up, and it was so fun to get to play improv games with humans for the first time in years.
You can watch the whole talk on YouTube or embedded below. You may want to fast-forward through the beginning, since the recording couldn't capture the off-stage improv shenanigans.
Other talks
Since it was a two-track conference, I could only attend half of the talks, but I did manage to watch quite a few interesting ones. Highlights:
- From Pandas to Polars: Upgrading Your Data Workflow
By Matthew Harrison, author of Pandas/Polars books. My takeaways: Polars looks more intuitive than Pandas in some ways, and Matt Harrison really encourages us to use chaining instead of intermediary variables. I liked how he presented in a Juypyter notebook and just used copious empty cells to present only one "slide" at a time. - The Five Demons of Python Packaging That Fuel Our Persistent Nightmare
By Peter Yang, Anaconda creator. Great points on packaging difficulties, including a slide reminding folks that Windows users exist and must have working packages! He also called out the tension with uv being VC-funded, and said that Python OSS creators should not have to take a vow of poverty. Peter also suggested a PEP for a way that packages could declare their interface versus their runtime. I asked him his thoughts on using extras, and he said yes, we should use extras more often. - F-Strings! (Slides)
By Mariatta Wijaya, CPython maintainer. Starts with the basics but then ramp up to the wild new 3.12 f-string features, which I had fun playing with afterwards. - Thinking of Topic Modeling as Search (Slides | Code)
By Kas Stohr. Used embeddings for "Hot topics" in a social media app. Really interesting use case for vector embeddings, and how to combine with clustering algorithms. - Master Python typing with Python-Type-Challenges
By Laike9m. Try it out! Fun way to practice type annotations. - PyTest, The Improv Way
By Joshua Grant. A 10-minute talk where he asked the audience what he should test in the testing pyramid (unit/integration/browser). I quickly shouted "browser", so he proceeded to write a test using Playwright, my current favorite browser automation library. Together with the audience, he got the test passing! 🎉 - Secret Snake: Using AI to Entice Technical and Non-Technical Employees to Python
By Paul Karayan. A short talk about how a dev at a Fintech firm used ChatGPT as a "gateway drug" to get their colleagues eventually making PRs to GitHub repos with prompt changes and even writing Python. They even put together a curriculum with projects for their non-technical colleagues. - Accelerating ML Prototyping: The Pythonic Way
By Parul Gupta. About Meta's approach to Jupyter notebooks, which involves custom VS Code integration and extensions. - Let's make a working implementation of async functions in Python 2.1; or, why to use newer Pythons
By Christopher Neugebauer, PSF. He managed to implement async in Python 1.6, using bytecode patching and sys.settrace. His conclusion is that we should use the latest Python for async, of course. 🙂 - Scrolling Animated ASCII Art in Python (Scrollart.org)
By Al Sweigart, author of many Python books. Very fun ideas for classroom projects!
Next year?
PyBay was a fantastic conference! Kudos to the organizers for a job well done. I look forward to returning next year, and hopefully finding something equally fun to talk about.
