Hello all, Applications are now being accepted for the 2017 Python in Astronomy conference. The conference will be held on 8th - 12th May 2017 at the Lorentz Center in Leiden, the Netherlands. Applications to attend Python in Astronomy 2017 are now open until December 9th 2016: Application Form https://goo.gl/forms/D8Zydnqhssn1J7vn1. The Python in Astronomy conferences aim to bring a wide variety of people who currently use, develop or teach people about Python packages in the context of all forms of Astronomy. Participant selection will be made with the goal of growingthe Python in Astronomy community and we particularly encourage requests to attend from junior astronomers and people who are new to contributing to open source software. This conference is neither intended to be an introduction to Python bootcamp nor only for expert-level Python developers, but we do expect all participants to have at least a basic familiarity with Python.
