Ensure to import 'open' from 'aiofiles' for asynchronous file operations

Quickstart

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.

import aiofiles
import asyncio

async def read_file():
    async with aiofiles.open('example.txt', mode='r') as f:
        contents = await f.read()
        print(contents)

asyncio.run(read_file())
