Hi, I am Mariatta

Mariatta

I’m an open source maintainer and contributor. As a Python core developer, my main focus is to improve the core workflow and documentation. I’m active in the Python community as an advisor and administrator for the Global PyLadies, co-founder of PyCascades. I’m chairing the PyCon US conference for the years 2023-2024. For my contributions to the Python and community, I’ve received the PSF Community Service Award in 2018 and Google Open Source Peer Bonus Award in 2017 and 2020.

Datetime and Hypothesis

I reviewed some issues that came to the CPython repo. There were a few interesting tickets related to the datetime module. These issues were discovered by Hypothesis, a property-based testing tool for Python. I’ve been hearing a lot about Hypothesis, but never really used it in production or at work. I watched a talk about it at PyCon US many years ago, and I even had ice cream selfie with Zac who maintains Hypothesis. Anyway, I’ve just been interested in learning more about Hypothesis and how it could solve issues not caught by other testing methods, and I think this is one of the perks of contributing to open source: getting exposed to things you don’t normally use at work, and I think it’s a great way to learn new things.

Recent Talks

PEP Talk
North Bay Python 29 July 2023

If you use Python, chances are you’ve heard of PEP 8, the Python style guide. But do you know what PEPs really are? PEPs are more than just a style guide. A PEP stands for Python Enhancement Proposal. It’s a proposal documentation for when you want to change the Python programming language in a big way, for example when you want to change the syntax of Python. Think of the addition of f-strings, the walrus operator, or the ExceptionGroup, those changes all started with a PEP. Let’s have a PEP talk, where you can learn about the PEP process, what needs a PEP and what doesn’t, and how you as community members can take part.

There's an API for That!

You might have seen bots like GitHub bots, Discord bots, Slack bots. How do these bots work? There’s an API for that! You can use third-party APIs to build web apps and automations, including bots. Come learn the best practices on how to work with APIs using Python.
