Ta bort ett enstaka dokument

# 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

Ta bort flera dokument samtidigt

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


# How many documents deleted?
res.deleted_count

Att ta bort dokument är permanent och kan inte ångras!
Kontrollera dina filter noga innan du tar bort!

Nu kör vi en övning!
