Delete Document

To delete one document, we use the delete_one() method. The first parameter of the delete_one() method is a query object defining which document to delete.

Note:

If the query finds more than one document, only the first occurrence is deleted.

Example

Delete the document with the address "Mountain 21":

Formula

import pymongo myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]

myquery = { "address": "Mountain 21" }
mycol.delete_one(myquery)

Delete Many Documents

To delete more than one document, use the delete_many() method. The first parameter of the delete_many() method is a query object defining which documents to delete.

Example

Delete all documents were the address starts with the letter S:

Formula

import pymongo myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]

myquery = { "address": {"$regex": "^S"} }

Formula

x = mycol.delete_many(myquery)

print(x.deleted_count, " documents deleted.")

Delete All Documents in a Collection

To delete all documents in a collection, pass an empty query object to the delete_many() method:

Example

Delete all documents in the "customers" collection:

Formula

import pymongo myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]

x = mycol.delete_many({})
print(x.deleted_count, " documents deleted.")
