aiofiles - 进行 异步文件io操作

import aiofiles

import asyncio

1、异步读取文件

async def read_file():
    async with aiofiles.open('/etc/ssh/ssh_config', mode='r') as f:
        contents = await f.read()
    print(contents)

loop = asyncio.get_event_loop()
loop.run_until_complete(read_file())

2、异步写入文件

async def write_file():
    async with aiofiles.open('test.txt', mode='w') as f:
        await f.write('Hello, world!')


loop = asyncio.get_event_loop()
loop.run_until_complete(write_file())
