Distinguished Service Award Granted To Naomi Ceder

Naomi Ceder, a longtime Python activist and organizer has been recognized with the PSF’s Distinguished Service Award. Naomi served on the PSF Board from 2015-2020, and as Chair from 2017-2020, supported the search for a new Executive Director last year and keynoted the most recent PyCon US in Salt Lake City.

The PSF’s Distinguished Service Award (DSA) is granted to individuals who make sustained exemplary contributions to the Python community. Each award is voted on by the PSF Board and they are looking for people whose impact has positively and significantly shaped the Python world. Naomi’s work with the Python community very much exemplifies the ethos of “build the community you want to see.” She seems to particularly enjoy taking on the hardest parts, getting a new initiative started and figuring out how to take an idea from the drawing board to a regular activity that we can’t imagine leaving out.

After receiving the award Naomi shared, "I'm so grateful for the recognition, and even more grateful for all of the support that our community has given me over the years. I'm excited to see a new generation of Python volunteers continue the work to make our community and the PSF more global and inclusive, and I'm looking forward to working with smaller communities as they grow and develop."

Over the years Naomi has taken on many leadership roles to make PyCon US successful and welcoming. She served as Chair of the Hatchery Program and she helped found PyCon Charlas, our Spanish language track. At different points in time, she’s also been the Co-chair of Sprints, an Organizer of the PyCon Education Summit and Chair for poster sessions at PyCon US. She also co-founded Trans*Code, an on-going series of hackdays (mostly) in the UK, which aims to build community and foster tech education and skills for transgender and non-binary folks. PyCon US and the global Python community would not look like it does without her tireless, largely behind the scenes work. Her deep thoughtfulness coupled with her energy is an immeasurable gift to the Python community. 

Curious about previous recipients of the DSA or wondering how to nominate someone? We got you.

PyCon US: Successful Return To In-Person In 2022

We held our first in-person event since 2019 in Salt Lake City last month and it was well-attended, celebratory, and safe. We had 1,753 in-person attendees and 669 online attendees. Of the in-person attendees, 1,153 were attending their first PyCon US ever – we hope they’ll all be back! In-person attendees were masked and we took care to add extra space to the expo hall, the dining areas, the session rooms and the job fair. For many community members, this was their first in-person conference or community event of any type in almost 3 years. There were a LOT of hugs and some very enthusiastic -- elbow bumps. 

You can take a look at PyCon 2022 by the numbers here. 

 Having joined the PSF as Executive Director just a few weeks before the event, this was a great opportunity to meet the community, including long-time volunteers, current and former board members, and hard-working local Python organizers from all over the world. It was also my first opportunity to meet the amazing PSF staff in person. Did you know that the PSF facilitates PyCon US with just 8 staff members? Their dedication to providing a space that is welcoming and fun, while also being safe and respectful, knows no bounds. The community is always first at PyCon US.  

We had lots of great talks and convened summits focused on Maintainers, Typing, Education, Packaging and the development of the Python Language. We also hosted Mentored Sprints for Diverse Beginners, the PyLadies Auction, four Lightning Talk Sessions, and two days of Sprints. We hit a few snags with a new AV team this year, but now most of the videos are up on our YouTube channel.  

This year’s event was a little more cautious, but it was really nice to see people. We’re actively looking for ways to better engage our online attendees next year and would welcome your ideas. Thanks to our many, many volunteers, especially three-time PyCon US Chair Emily Morehouse! Thank you also to our wonderful sponsors, many of whom not only help us put on PyCon US but also support the Python Programming Language throughout the year!! 

Mark your calendar for PyCon US 2023 from April 19th to April 27th, 2023 both in Salt Lake City or online. If you are interested in talking about sponsorship opportunities for 2023, please drop us a line. And we are always looking for more volunteers, so if you’d like to be part of a future event as a volunteer, just let us know.

PEP 679: Allow Parentheses In Assert Statements

This pep proposes to allow parentheses surrounding the two-subject form of
