使用motor删除mongo数据

motor 提供了delete_many 方法用于批量删除mongo数据，它接收查询条件，所有符合查询条件的数据都会被删除

import pprint
import asyncio
import motor.motor_asyncio

uri = "mongodb://kwsy:123456@localhost:27017/app"
client = motor.motor_asyncio.AsyncIOMotorClient(uri)

db = client.app
user = db.user


async def do_delete():
    result = await user.delete_many({'name': '小红'})
    print(result.deleted_count)


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