Exception Groups and except*
Irit Katriel

Python 3.11 introduces new features that make it possible to raise and handle multiple unrelated exceptions. This talk briefly covers what they do and how they work, and answers a frequently asked question: why we needed to add new language syntax to handle exception groups.

Introduction to Data Analysis Using Pandas
Stefanie Molin

Data often doesn’t come in the best format for analysis, and understanding it enough to extract insights requires both time and the skills to filter, aggregate, reshape, and visualize it. This session will equip you with the knowledge you need to effectively use pandas to make this process easier.

HPy: a better C API for Python
Ronan Lamy

HPy is a new C API for Python. Unlike the standard one, it isn't tied to CPython implementation details. It is therefore fully compatible with alternate implementations and with any future changes to CPython itself.

I hate writing tests, that's why I use Hypothesis
Cheuk Ting Ho

Ok, I lied, I still write tests. But instead of the example-based tests that we normally write, have you heard of property-based testing? By using Hypothesis, instead of thinking about what data I should test it for, it will generate test data, including boundary cases, for you.

How to wag a dog
Daniele Procida

Dogs wag their tails. When the opposite happens, it represents a disturbing, problematic reversal of the proper order. But not in software and its documentation! I believe the tail of documentation can and should wag the dog of software, and I'll show just how powerful this tail can be.

Do not trust my [or any] computational research.
Vincent Knight

In research, peer review is considered a pillar of trust. This is problematic. A lot of research is, at best, not reproducible or, sometimes, even wrong, despite peer review. This talk will discuss the origins of peer review, problems with peer review and some things that could be better.

Bulletproof Python – Property-Based Testing with Hypothesis
Michael Seifert

Property-based testing is a great benefit to the robustness and maintainability of your software. Yet, the technique is still vastly underused in the Python community. The workshop gives a hands-on introduction to Hypothesis and practices different approaches for writing property-based tests.

Using python to create a prototype for web accessibility research
Peter Johnson

According to the WHO over 1 billion people live with some form of disability; almost everyone is likely to experience some form of disability at some point.

Living With Technical Debt: Acknowledge It, Specify It, Reduce It
Reka, Tim Gilboy

Technical debt is the elephant in the room: complex engineering problems meet awkward organizational issues. To make it more tangible, we'll divide it into 3 categories and discuss engineering and business strategies for each:

  • Gather info about vague issues.
  • Express antipatterns as code.
  • Automatically fix straightforward issues.

Meta Generators: Playing Safe with Long Sequences
Alastair Stanley

Let’s take a closer look at generators and why you may not be getting your expected improvements. Sometimes the memory benefit is negated by necessity; sometimes it's by mistake. "Meta generators" can solve this problem, allowing a much wider range of safe, fast operations on very large generators.

Property-Based Testing the Python Way
Emma Saroyan

What if I told you that you could write simpler tests but get better results?

What if I told you can automatically generate your test data?

This may sound difficult to your traditional testing approach but can be easily done with Hypothesis, the Python library used for property-based testing.
