删除单个文档

# Setup
from pymongo import MongoClient
client = MongoClient()
mov = client.film.movies


# Delete document that matches filter, similar to find_one()
res = mov.delete_one({ "title": "gladiator" })


# How many documents were deleted?
res.deleted_count

一次删除多个文档

# Delete all really bad movies
res = mov.delete_many({ "rating": { "$lt": 5.0 } })


# How many documents deleted?
res.deleted_count

删除是永久的，无法撤销！
删除前请再次确认过滤条件！
