Learn about data
On Feb 14, join ~150 devs at SF Python's presentation night and learn more about data. Our generous sponsor Yelp will also provide pizza and beer for the evening. Please register via our ticketing partner Tito: ( PROGRAM Lightning talks (5 mins) Main talk (~30 mins + Q&A) TALK #1 - Understanding A/B test analysis by simulating data ABSTRACT A/B tests are at the heart of every data driven company, but how well do we understand the statistical tests available to us, especially when the data are far from textbook examples? Experimentation is a great way to learn and get an intuitive feel for the math underlying A/B test analysis. By simulating data and turning a few knobs, we can observe how test analysis results behave. Topics covered: - Sampling from random distributions using numpy and scipy. - Parametric and non-parametric tests in scipy. - Efficient randomization tests in Python. - Visualization with matplotlib, Bokeh, and Holoviews. - Interactivity with Jupyter notebooks and ipywidgets. BIO Dennis O'Brien is Director of Data Science at GSN Games where he creates models, builds pipelines, wrangles data, runs experiments, and extracts insights from data. He has been in the video game industry for almost 20 years and has used Python in every job along the way. TALK #2 - Deep Learning with PyTorch ABSTRACT 1. What's Deep Learning and how is it different from Machine Learning 2. What's PyTorch and why are people excited about it. 3. What are the important differences between PyTorch and other frameworks like Tensorflow / Keras. 4. Walk through a few examples to highlight the API and design choices that sets PyTorch apart. BIO Ramesh Sampath is an Machine Learning Engineer with a background in software engineering. He loves to build Machine Learning models and deploy them as API services. Although he's been working on Deep Learning models recently using PyTorch and TensorFlow, he has special affinity for Numpy, Pandas and Scikit-Learn. He co-wrote a python ML Library called ML-Insights to introspect Scikit-Learn Models ( 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!
