Python packaging can be a scary and confusing endeavor. The ecosystem can be thorny and filled with many decisions around which tool or approach to use. You’re also likely to get pricked by an approach or tutorial that doesn't work as expected. However, the packaging journey doesn’t have to be prickly - particularly for pure Python packages. By building community consensus around user goals and moderating healthy discussion, pyOpenSci is paving a smooth, thorn-free path for successful packaging. This talk presents pyOpenSci’s people-first approach to guiding the scientific community through thorny packaging decisions. First, we engaged with the broader community to understand packaging needs. Second, we brought together packaging experts, tool maintainers, and beginning-to-advanced users to successfully build consensus around tools and best practices. Community outreach helped us understand both user needs and the packaging tool ecosystem. Finally, consensus around tools and needs was transformed into accessible recommendations in our community-driven Packaging Guide. Guidebook pull requests go through extensive, open community review with 38 people and thousands of comments contributing to the guidebook’s current state. Careful moderation ensures healthy and productive conversations and also drives consensus-building around beginner-friendly content. Our guidebook’s development process allows us to harness community expertise to create an accessible and accurate packaging guide that smooths out the packaging path. You will will walk away from this talk with a better understanding of: Why consensus-building and user-focused content development is critical for tackling thorny topics such as packaging. How to decide which packaging tools satisfy your packaging needs. Where to find more information and support around packaging. You don’t have to package alone. The vibrant Python community is here to help. Slides: https://pycon-assets.s3.amazonaws.com/2024/media/presentation_slides/34/2024-05-18T13%3A27%3A50.285095/pycon-talk-2024.pdf

Southeast Alaska is a temperate rainforest, and landslides have been happening here for thousands of years. But shifting rainfall patterns have increased the frequency of landslides, with catastrophic results. In the last 8 years, three different towns in our region have experienced fatal landslides. After a major landslide in 2015, a number of local people with experience in the outdoors and in various scientific fields noticed a possible correlation between river levels and landslide activity. Our main river has a small watershed, so it responds rapidly to periods of heavy precipitation. Using Python, I was able to investigate the question we all kept coming back to: Is the correlation between changing river levels and landslide activity strong enough to serve as the basis for predicting landslides? Using historical readings from a local river gage, a set of conditions was identified that correlate meaningfully with landslide activity. In about 12 events where the river met those conditions, at least 5 were associated with known landslides. I posted a landslide-risk monitoring tool in 2021, which provides a visual indication of when the river is behaving in a way that correlates with previously known landslide events. This tool is used by many community members to assess the ongoing risk of landslide activity during heavy rain events. Just as importantly, it helps people let go of anxiety when we're experiencing rain that feels heavy, but isn't actually associated with landslide risk. This talk will show how Python's vast ecosystem supports the entire citizen-scientist lifecycle, from idea to public-facing resource.

What makes a good API for a library? Or more importantly, what makes an API bad? Implementing an API is an art. It’s the connection between the user and the library itself. How can we optimize that connection to make the experience more pleasing? What makes a user reach for one library over another? What goes into an ergonomic API? This talk will discuss what makes an API good: simplicity, consistency, and flexibility. We will apply those principles by iterating and improving on a real world example, ending with a library that is delightful to work with.

Modifying existing code is just the worst. It's a tangled mess of dependencies, you don't know the original author's intent, and simple changes feel like they break the world. But it can be better. Wouldn't it be nice to be in a codebase where you primarily added new code and didn't touch the old stuff? We can achieve this by viewing your code through the lens of extensibility. In this talk, you'll learn what extensibility means, and some common patterns for making your code more extensible. We'll take a hard look at the Open-Closed Principle and how to deal with a mess of dependencies. We'll then walk through how to make your code composable so that it's easier to build up abstractions. We'll finish off by looking through two architectural styles that promote extensilbility: event-driven architectures and pluggable architectures. Software is going to change (that's why we call it "soft"ware). That's inevitable. How your codebase withstands that change is up to you. Don't write a tangled, fragile mess that is incomprehensible. Make it easy to extend, and you'll greatly extend the lifetime of your products.
