刪除單一文件

# 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

同時移除多筆文件

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


# How many documents deleted?
res.deleted_count

刪除是永久動作，無法復原！
在刪除前，務必再次確認條件！

一起來練習吧！
