## What it is
The historical development repository for asyncio, Python's standard library for writing concurrent code with async/await syntax. Development has moved into CPython, so this repo is closed and the library now ships with Python 3.

## Use cases
- run coroutines concurrently in python
- write high-performance async network servers
- manage subprocesses asynchronously
- build async task queues
- handle io-bound concurrent workloads with async await

## When to choose
- you need async/await concurrency in Python 3 via the standard library
- you are building io-bound network services or async frameworks on Python

## When to avoid
- you expect to install or contribute to this repository - it is closed and merged into CPython
- you need asyncio on Python 2 - the PyPI backport is deprecated
- cpu-bound parallelism is your goal - use multiprocessing instead

## Facets
- artifact type: library
- maturity: abandoned
- function: concurrency, networking, http-server, websocket, scheduling
- domain: developer-tools, networking, backend, microservices
- platform: python, cross-platform
- tags: async-await, event-loop, stdlib, historical-repository, io-bound
