Talk Python To Me #447: Parallel Python Apps with Sub Interpreters
Feb 3, 2024
Eric Snow and Anthony Shaw discuss the exciting developments in Python, such as sub-interpreters, Faster CPython, async work, and the adoption of typing. They explore the concept of subinterpreters in Python processes, highlighting the benefits of isolation and enabling concurrency. The discussion also touches on consolidating global state, using sub interpreters as an API for concurrent futures, managing Python processes with sub interpreters, and implementing multi-phase init in extension modules to support sub-interpreters in Python.
