asyncstdlib-fw

What it is and what it does

asyncstdlib-fw is a fork of asyncstdlib that re-implements Python's standard library functions to work seamlessly with async callables, iterables, and context managers. It provides async versions of familiar tools like zip, map, enumerate, functools.reduce, and itertools operations, letting developers use idiomatic patterns in async code without writing custom wrappers.

The package has no runtime dependencies and works with any async event loop—asyncio, trio, or custom implementations. It handles async iterator cleanup safely and includes utilities for integrating synchronous code into async programs. With zero external dependencies and production-stable status, it's a lightweight addition to async Python projects.

Use it for:

• Iterate over multiple async iterables in parallel using async zip or map without manual coroutine management.
• Enumerate async iterables to track position while consuming async generators or streams.
• Group or reduce async data streams using async versions of itertools and functools operations.
• Safely integrate existing synchronous helper functions into async codebases with minimal refactoring.
• Build async pipelines that combine multiple standard library patterns in a single expression.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides async-compatible versions of Python standard library functions like zip, map, enumerate, and itertools operations, enabling them to work with async iterables and callables.

Yes. Zero dependencies, permissive MIT license, active maintenance, and production-stable status make this a low-risk addition. Install if you work with async iterables and want to avoid writing custom wrappers for standard operations—the library directly solves that problem. The fork designation warrants checking whether it diverges from upstream in ways that matter to your use case.

Install

Installing asyncstdlib-fw

Before you install

Low friction installation with no runtime dependencies. Actively maintained with recent commits and production-stable status across Python 3.8–3.13.

License in practice

MIT license permits free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Quickstart

pip install asyncstdlib-fw

import asyncstdlib

async def example():
    async_iter = asyncstdlib.enumerate(some_async_iterable)
    async for index, item in async_iter:
        print(index, item)

Requires Python 3.8 or later.

Verify before relying

• Whether the fork maintains feature parity with the original asyncstdlib or introduces breaking changes.
• Performance characteristics compared to manual async iteration patterns.
