What we’re about
Anybody that appreciates the PyData/NumFOCUS mission - Bringing the world of open source data science & scientific users together! - is greatly appreciated to join our meetup group and if you can and want, also help out in some way to make our meetups happen and great!
We wish to have interesting talks in a friendly and informal setting with snacks/food and beer, so that people have a reason to stay and get to know each other.
Also, we aim to be an accessible, community-driven meetup (and eventually conference), with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases.
Please contact us if you can provide a room, interesting talks, food, drinks, or alike. You or whom you are associated with could also become an official sponsor (with a little banner, link, and mention during meetups) of our group!
To centrally, efficiently, and transparently manage suggestions, current tasks/problems, and just in general the continuous organization/milestones of individual meetups as well as the overall group, we have a GitHub repo.
PYDATA
PyData brings together both users and developers of data analysis tools to share ideas and learn from each other. The goals are to provide data science enthusiasts, across various domains, a place to discuss how best to apply languages and tools to the challenges of data management, processing, analytics, and visualization. We are focused around the Python ecosystem, but are also open to other languages and relevant topics that may help to better solve the evolving challenges in data management, processing, analytics, and visualization.
PyData groups, events, and conferences aim to provide a venue for users across all the various domains of data analysis to share their experiences and their techniques. PyData is organized by NumFOCUS.org, a 501(c)3 non-profit in the United States.

Talk #1: Rust in the data science and machine learning stack
The Python ecosystem has seen the emergence of several high-profile tools and libraries developed with the Rust programming language, including the ruff linter/formatter, the uv package/project manager, the polars dataframe library, the pydantic data validation library, and HuggingFace's tokenizers.
This talk will explore the role that Rust can play in the data science and machine learning stack, through case studies, high-level considerations, and practical examples. It will include a concise introduction to the language and techniques for integrating it with Python.
We aim to give attendees the tools to understand when it makes sense to reach for Rust, particularly in the context of data-intensive applications, and how to do so effectively.
Talk #2: Dataframely — A declarative, polars-native data frame validation library
In this talk, we will talk about the motivation behind building dataframely in more detail and lead the audience through its key features. We will also touch upon our learnings in developing robust data pipelines that establish clear contracts for the design of data transformations. In our experience, this significantly improves communication among developers and comprehensibility of the entire pipeline.
