Learn more about new language features and a new language!
On March 14, join ~150 devs at SF Python's presentation night and learn more about new language features and a new language :) Our generous sponsor Yelp will also provide pizza and beer for the evening. Please register via ( If you'd like to give a 5 mins lightning talk or 10-15 mins short talk at this or upcoming meetups, please submit your talk idea here ( *PROGRAM* — Lightning talks (5m) Lessons learned from migrating to Python 3 at CMB, by Ann Paul Narrative Logging with Eliot, by Stephan Fitzpatrick — Short talk (15m + Q&A) Nim for Python programmers, by Abhishek Kapatkar — Main talk (~40 mins + Q&A) Trio: Async concurrency for mere mortals, by Nathan Smith *ABSTRACT AND BIO* — Trio: Async concurrency for mere mortals by Nathan Smith Concurrent programs are super useful: think of web apps juggling lots of simultaneous downloads and websocket connections, chatbots tracking multiple concurrent conversations, or web spiders fetching pages in parallel. But *writing* concurrent programs is complicated, intimidating to newcomers, and often challenging even for experts. Does it have to be? Python is famous for being simple and straightforward; can Python make concurrent programming simple and straightforward too? I think so. By carefully analyzing usability pitfalls in other libraries, and taking advantage of new Python 3 features, I've come up with a new set of primitives that make it dramatically easier to write correct concurrent programs, and implemented them in a new library called [Trio]( In this talk, I'll describe these primitives, and demonstrate how to use them to implement a basic algorithm for speeding up Bio: Nathaniel J. Smith is a cognitive scientist and open-source developer, currently at the UC Berkeley Institute for Data Science. He's a core developer on NumPy and CPython, brought the '@' operator to Python, co-designed matplotlib's "viridis" colormap, instigated the creation of "manylinux" wheels, and writes too many PEPs. He won't be talking about any of that. — Nim for Python programmers, by Abhishek Kapatkar Ever wondered if there existed a language as expressive as Python and as efficient as C/C++? Look no further then. Nim is a statically typed, compiled language with a focus on efficiency. It is versatile and borrows much of its constructs and standard library design from Python Bio: Abhishek Kapatkar works at Netflix on Machine learning infrastructure team, whose mission is to make using data easy and efficient. He and his team are responsible for envisioning how the data platform allows data scientists to make Netflix's service even better. He enjoys product development, programming language design, and is passionate about the usage of technology for the social good and currently serves as a San Francisco chapter leader for AGENDA: 6:00p - Check-in and mingle, with food provided by our generous sponsor Yelp! 7:05p - Welcome 7:10p - Announcements, lightning talks, and main talk 7:30p - Doors Close 8:20p - More mingling 9:30p - Hard Stop **SF Python is run by volunteers aiming to foster the Python Community in the bay area. Please consider making a donation ( to SF Python and saying a big thank you to Yelp for providing pizza, beer and the venue for this Wed's meetup. **Yelp sees 89 million mobile users and 79 million desktop users every month. Keeping everything running smoothly requires the best and brightest in the industry. Their engineers come from diverse technical backgrounds and value digital craftsmanship, open-source, and creative problem-solving. They write tests, review code, and push multiple times a day. Come out and talk to them.

What we're about

Public Group

SF Python is your opportunity to grow your technical career by learning and sharing what you know with other local Python developers!

Organized by a handful of volunteers with the help of some faithful sponsors and your generous donations, we host:

2 monthly meetups (

- Presentation Night on the 2nd Wednesday of each month features intermediate to advanced level tech talks from Python Software Foundation members, core developers of open-source projects, and local software engineers.

- Project Night on the 3rd Wednesday of most months offers a chill evening to hack on projects, get questions answered, mentor other devs, or attend a tutorial. It's usually held at various companies in SF so you get to sample how different companies are using Python.

PyBay, a yearly regional Python Conference (

PyBay is the local version of PyCon. You can save on travel costs and still have an experience of the conference that serious python developers aspire to attend. PyBay is a 3-day weekend conference in August featuring 40 talks and 400+ attendees.

An annual holiday party (

We think you'd agree that if you have been coming to SF Python's events, you have been advancing in your field. So come celebrate the year with us. We will listen to more amazing speakers while enjoying great food and drinks. Who knows, if we continue to get lucky, we will have more amazing entertainers to help us celebrate the year.

Why do we put these events up?

We believe there is power in in-person interactions. We believe in learning, sharing, and helping each other out. And we have seen the results. We have heard stories of people getting their problems solved because of the talks and the people they met at our events. We have witnessed people grow in their career, from receiving their first internship to landing their first speaking gig at conferences. We have even heard companies migrating to a different platform/technologies after attending our conference.

We look forward to your joining this awesome community - be it attending our events, giving a talk (, being a sponsor or supporting us financially!
