The 2019 Python Language Summit

A. Jesse Jiryu Davis / · Updated

The Python Language Summit is a small gathering of Python language implementers, both the core developers of CPython and alternative Pythons, held on the first day of PyCon. The summit features short presentations from Python developers and community members, followed by longer discussions. The 2019 summit is the first held since Guido van Rossum stepped down as Benevolent Dictator for Life, replaced by a five-member Steering Council. LWN.net covered the proceedings from 2015 to 2018; this year the PSF has chosen to feature summit coverage on its own blog, written by A. Jesse Jiryu Davis.
