What we learned at PyGrunnX
We attended the 10th edition of PyGrunn, a Python (and friends) conference in Groningen, NL. Here's what we learned.

PyGrunn
PyGrunn is a conference about the Python programming language and its uses. It is also about related subjects, hence "and friends". As this was the 10th edition, it was dubbed PyGrunnX.
It was a great experience to be at a real live conference again. Discussing stuff with others, meeting with ex-colleagues, making new contacts and sharing knowledge, we've missed it.
Talks
To get an idea about the diversity of subjects, have a look at the schedule.
Coen spoke about live blogging with Wagtail Live.
Kees spoke about better code reviews (slides).
Lessons learned
Without further ado, here are the learnings:
- When doing a live demo during a talk, always have a plan B.

- You can change a callable's signature.
- ω
- Pattern matching in Python 3.10 is cool.
- More understanding of
self
- Shorter is often quicker
- Maths is hard
- Getting up at 6 sucks and Groningen is a long way from Arnhem.
