Voices
Enjoyable for Python beginners and veterans alike. Sessions on data science and ML are particularly rich.
The sprint day where you can actually contribute to OSS is amazing. Connections between developers form naturally.
Since the event moved to regional cities, it has become enjoyable as a trip. You can also savor Hiroshima's cuisine.
From the pre-party through Day 2, studying Python 3.14 features and meeting engineers from abroad (from Shunsoku's report, in Japanese)
Joined on the sponsor side, connecting with the Python community through booth events and English conversations (from pika's report, in Japanese)
