PyCon US

The Python Steering Council is a 5-person elected committee that assumes a mandate to maintain the quality and stability of the Python language and CPython interpreter, improve the contributor experience, formalize and maintain a relationship between the Python core team and the PSF, establish decision making processes for Python Enhancement Proposals, seek consensus among contributors and the Python core team, and resolve decisions and disputes in decision making among the language. Presented by: Barry Warsaw Donghee Na Gregory P Smith Pablo Galindo Salgado (Steering Council member not present: Emily Morehouse) Python Steering Council - Barry Warsaw, Donghee Na, Gregory P Smith & Pablo Galindo Salgado

#PyConUS recordings continue to go up! One freshly posted session is the annual Steering Council presentation, with updates on Python 3.14 🥧, free threading, and more. As Pablo would say, WOW.

All code needs a user interface. That might be an API, or a web page - but these days, many users will expect an app that they can install on their laptop, or on their phone. But how do you build a native application in Python? And do you need to build a different version of your app for every device and operating system you want to support? In this hands-on tutorial, you'll learn how you can use the BeeWare suite of tools to build a graphical user interface for your code, and deploy that code as a desktop app, and as a mobile app - all from a single Python codebase. You'll learn how to integrate third-party libraries like NumPy into your app, and how to customize the appearance of your packaged app. You'll also learn how you can access device hardware (such as cameras and GPS) in your...

In this tutorial, we'll discuss how to build the basic components that make up a modern digital synth from scratch! In the process, learn some DSP and audio programming concepts! By the end, you’ll be able to make your own tunes with Python! We will start with theory, then work through Jupyter notebooks both individually and as a group. This tutorial will be a lot of fun if you’re a musically inclined Python programmer. As someone interested in music, you will discover the components that make up a synthesizer by literally building & making music with it, and as someone interested in Python, you’ll learn a lot about audio programming and signal processing techniques.

Full Tutorial Title: Reimplementing the module `itertools` for fun and profit You know how to use a `for` loop in Python. But do you know HOW it works Do you know why it is that you can write `for` loops with `range`, `lists`, `strings`, `zip`, and `enumerate`? What's the machinery that makes that work? And have you noticed how `range(1)` and `range(99999999999999999)` take exactly the same time to run? There's something lazy about the built-in `range`... But what does “lazy” even mean? In the tutorial “Reimplementing the module `itertools` for fun and profit” you'll learn how to answer all of these questions, and much more, through the lens of the module `itertools`. The module `itertools` is implemented in C, but in this tutorial you'll reimplement it in pure Python! And you'll do that for two reasons. First, because it's an excellent, fun challenge...And on top of that, because it's surprisingly... PyCon US 2025 Tutorial Sneak Peek: "Reimplement `itertools` for fun & profit" Rodrigo Girão Serrão

Codyssey is a 3-hour workshop where you’ll learn about the control system programming model and implement simple systems in Python to autonomously play various games. You’ll observe the behavior of your system in a visual environment, and compete with other participants to solve as many games as you can. Along the way, you’ll have to think creatively and practice translating your intuition into code. During the workshop, I’ll mentor individual participants/pairs; after the competitive part, I’ll live-code solutions for chosen challenges while demonstrating how to apply the control system programming model. Each challenge will have you implementing a function that runs dozens of times a second, deciding which action to take. Come hone your Python skills, adapt to a new way of thinking, and tackle some epic challenges! Joining us at PyCon US 2025?

Are you confused or frustrated by comprehensions? Do you wonder about their syntax -- or even why we would use them in the first place? In my "Comprehending comprehensions" tutorial, you'll learn not only how to write comprehensions, but (more importantly) why and when to do so. We'll go through list, set, and dict comprehensions, as well as the harder-to-understand nested-comprehension syntax and generator expressions. The tutorial won't use slides: Rather, I'll use a notebook to write notes and code in real time, allowing me not only to demonstrate the code, but also to answer your questions in real time. (The notebook I use will be available both while the tutorial is going on, and afterwards.) I've been teaching Python for many years, and comprehensions remain one of the topics that most confuse developers, regardless of how long they've been using Python. After attending my tutorial, you'll not only know... PyCon US 2025 Tutorial Sneak Peek: "Comprehending Comprehensions" - Reuven M. Lerner
