annotated-types/annotated-types

GitHub

annotated-types provides reusable metadata objects (for use with `typing.Annotated`) that describe common data constraints like numeric bounds (Gt, Ge, Lt, Le), interval bounds, length limits (Len, MinLen, MaxLen), timezone restrictions, units, and runtime-check predicates. It’s useful for standardizing constraint annotations so other tools and libraries can interpret them consistently without treating `Annotated[T, x]` differently from `T`.

fastapi/annotated-doc

GitHub

annotated-doc is a small Python library that lets you attach documentation strings directly to function parameters, class attributes, return types, and variables using typing.Annotated. It is useful for keeping symbol documentation in code and enabling tools to extract consistent parameter docs for reference-style documentation, including support used by FastAPI reference documentation.

omnilib/aiosqlite

GitHub

aiosqlite provides a friendly asynchronous interface to SQLite databases for Python’s AsyncIO. It mirrors the standard sqlite3 connection and cursor APIs with async methods and context managers, letting you run queries and fetch results without blocking other coroutines. It can also replicate many advanced sqlite3 features.

Last release: 2025-12-23

aio-libs/aiosignal

GitHub

aiosignal is a Python asyncio helper for managing a list of registered asynchronous callbacks (“signals”). It lets you append callbacks, then freeze the signal to prevent changes, and finally trigger all registered callbacks with await sig.send(data). Useful for coordinating event-style callback behavior in asyncio projects, including examples referenced in aiohttp’s advanced web server documentation.

omnilib/aioitertools

GitHub

aioitertools provides asynchronous versions of familiar Python itertools and builtins-style helpers, for AsyncIO and mixed iterables (including standard iterators and async iterators). It’s useful when you want one unified, familiar interface for iterating, mapping, chaining, and slicing iterable data in async code.

Last release: 2025-11-06

aio-libs/aiohttp

GitHub

aiohttp is an asynchronous HTTP client and server framework for asyncio and Python. It supports both HTTP and WebSocket use cases, including a Web server with middleware and pluggable routing, useful for building async services and clients.

Last release: 2026-06-07

aio-libs/aiohappyeyeballs

GitHub

aiohappyeyeballs provides a Happy Eyeballs style connection helper for asyncio use cases where you already have a list of addrinfo and not a DNS name. It is useful when you do DNS caching or resolve names via other mechanisms, such as zeroconf, and want to connect using those pre-resolved addresses.

Last release: 2026-05-20

aio-libs/aiobotocore

GitHub

aiobotocore provides asyncio support for the botocore AWS SDK, using aiohttp to make botocore-style clients work in async Python. It is useful if you want to call Amazon services such as S3 asynchronously, including examples for streaming responses, paginators, and async context manager usage.

Last release: 2026-05-09

terricain/aioboto3

GitHub

aioboto3 is an async AWS SDK for Python that wraps boto3 resources to run on an aiobotocore async backend. It lets you use higher-level boto3 client and resource APIs in an async manner, useful for Python microservices that need AWS access without blocking the event loop. It uses async context managers for client and resource creation, and includes some async workarounds for boto3 operations like S3 upload and download.
