aiofiles is a Python library that provides asynchronous file operations for asyncio applications, enabling non-blocking file I/O. The current version is 25.1.0, released on October 9, 2025. The library follows a regular release cadence, with updates approximately every few months.

This example demonstrates how to asynchronously read a file using aiofiles. The 'open' function from aiofiles is used to open the file, and 'await' is used to read its contents without blocking the event loop.
Upgrade to Python 3.9 or later to continue using aiofiles.
Always use 'async with' for asynchronous context management with aiofiles.
Ensure that the file specified in aiofiles.open() exists at the given path in the execution environment.
Ensure that the file specified in `aiofiles.open()` (e.g., 'example.txt') exists in the directory where the script is being executed, or provide the full absolute path to the file.
Install the library using pip: `pip install aiofiles`.
Ensure that `aiofiles.open()` is used within an `async` function and with the `async with` keyword: `async with aiofiles.open('filename', mode='r') as f:`.Always `await` calls to `aiofiles` functions and methods that return coroutines, such as `aiofiles.open()`, `file.read()`, `file.write()`, or `aiofiles.os.remove()`: `await file.read()` or `await aiofiles.os.remove('file.txt')`.Import `os.path` separately for path-related operations, as it is synchronous and generally safe to use outside of `aiofiles.os`: `import os.path` and then `os.path.join(...)`.
