Title: P1: Pytup Yandex meetup [2023-12-17 Sun] support in Python as speed up of asyncio and new sub-interpreters feature was introduced in 3.12. Some of them joked that Python will become fully concurrent in 3.7. ✯ PEP 684: A Per-Interpreter GIL - currently only available through the C-API, Python API will be in 3.13. So the new GIL crated in current thread and it takes full advantage (and risks I suppose) of multi-CPU. ✡ #python #dailyreport #conference
