What to expect

Join the data science community in Southampton for PyData Southampton's 23rd meetup — an evening of Python-focused talks exploring cutting-edge tools and techniques in scientific computing, data processing, and machine learning. This monthly gathering brings together developers, data scientists, researchers, and Python enthusiasts to share knowledge and connect over shared interests in the PyData ecosystem.

Featured Talks

Getting Started with PyO3 by David Hewitt, PyO3 maintainer

Discover how Rust can supercharge your Python applications through PyO3. The scientific Python ecosystem relies heavily on native packages — numpy runs on C, while modern data processing powerhouses like Polars and Pydantic leverage Rust and PyO3 for performance. This session provides a practical introduction to giving your Python code a native core using Rust. You'll explore how PyO3 works under the hood and see live examples of Rust code running seamlessly inside Python applications. Perfect for Python developers curious about performance optimization and those wanting to understand what powers the next generation of data tools.

A second main talk and lightning talk sessions are also scheduled, with speakers to be announced. Lightning talks offer quick-fire presentations on emerging tools, techniques, or interesting projects — keep an eye on the speaker proposal form if you'd like to share your own work with the community.

What to Expect

This meetup welcomes everyone from Python beginners to experienced data scientists. The evening includes structured presentations followed by networking opportunities where you can discuss projects, ask questions, and connect with fellow practitioners. Doors open at 6:30 PM for early arrivals, with talks beginning promptly at 7:00 PM. For those wanting to continue conversations, the group relocates to a nearby pub from 9:00 PM onwards.

Carnival UK generously hosts the event at their Southampton offices and provides pizza and drinks for all attendees. Additional sponsors include NumFOCUS, which promotes open-source scientific computing, and JetBrains, who provide IDE subscription prizes for community members.
