PyCoder's Weekly | Issue #695
Briefly

Subinterpreters in Python allow for running multiple interpreters within a single process, improving isolation without needing multiple processes. Asyncio facilitates asynchronous programming with support for coroutines and allows easy management of concurrent tasks. Pytest's parametrize feature simplifies running tests with various inputs despite its complexity. PEP 792 introduces project status markers to improve metadata communication about a project's state on PyPI. This includes indicating if a project is archived or quarantined. The recent releases of Python versions and the status of Unicode character services are also noteworthy.
Subinterpreters provide a means to run separate Python interpreters within a single process, allowing for better isolation. However, the community currently lacks a deep understanding of how to effectively implement them.
Asyncio enables the implementation of asynchronous programming in Python, providing a framework to handle coroutines and awaitable tasks. It's essential for developing efficient, non-blocking applications that require concurrent I/O operations.
Pytest's parametrize feature allows developers to run the same test with multiple sets of input data, making it a powerful tool for ensuring code correctness. Although it may appear complex at first, understanding its syntax greatly enhances testing capabilities.
PEP 792 introduces project status markers in PyPI as metadata that provides insight into the state of projects, helping users understand if a project is archived, quarantined, or in other states.
