Matt Craig was kind enough to share his summary of the recent Python in Astronomy conference, for which NumFOCUS provided a grant. Read on below!

#pyastro17 brought together 54 participants from five continents for a wide-ranging workshop on Python in Astronomy. The workshop was held at the Lorentz Center at Leiden University in the Netherlands. Like previous Python in Astronomy workshops in 2015 and 2016, the workshop was a mix of talks in the morning and “unconference” sessions in the afternoon, with one of the days dedicated to sprints and hacks.

Talks

One of the fun things about this workshop is the range of astronomical topics, from a talk on archeoastronomy by Eduardo Rodas about using software to model the horizon at archaeological sites to test hypotheses about alignment of structures with astronomical objects (Python is great at non-destructively removing trees, for example) on the first day to M. Emre Aydin’s talk on optimizing python loops the last day.

The keynote presentation by Azalee Bostroem on starting a code review community with her research group nicely captured the spirit of the conference: hands-on learning in the service of building a broader community. Within a week of leaving the conference, Ekaterina Ilin initiated a code review group with her fellow graduate students.

Unconference sessions

A typical unconference schedule looked like this:

In late morning, participants proposed ideas, volunteered to help out and voted for the sessions they wanted. These were a mix of tutorials, demonstrations, conceptual discussions and coding sessions. An unconference proceedings is being prepared and will be available soon on the #pyastro17 site.

Hack day

The hack day this year included a huge range of topics; take a few minutes to check out the full list (this is a work-in-progress document, and will be incorporated in the unproceedings). Some highlights:

  • at least 15 new pull requests, many by first-time contributors.
  • 13 or 14 new repositories created in GitHub (search for the pyastro17 label).
  • several packages released for the first time on PyPI.

One of the goals in selecting the 55 workshop participants out of a pool of over 180 qualified applicants was ensuring a diverse group of people were able to attend. Though diverse in the context meant many dimensions of diversity — more details are in a
