Python Mongodb – Delete_many()
MongoDB is a general-purpose, document-based, distributed database built for modern application developers and the cloud. It is a document database, which means it stores data in JSON-like documents. This is an efficient way to think about data and is more expressive and powerful than the traditional table model.
Delete_many()
Delete_many()
is used when one needs to delete more than one document. A query object containing which document to be deleted is created and is passed as the first parameter to the delete_many().
Sample Database:
Example 1: Deleting all the documents where the name starts with ‘A’.
import pymongo # Connecting to the database mydb = client[ "GFG" ] # Connecting the to collection col = mydb[ "Geeks" ] query = { "Name" : { "$regex" : "^A" }} d = col.delete_many(query) print (d.deleted_count, " documents deleted !!" ) |
Output:
2 documents deleted !!

Example 2:
import pymongo # Connecting to the database mydb = client[ "GFG" ] # Connecting the to collection col = mydb[ "Geeks" ] query = { "Class" : '3' } d = col.delete_many(query) print (d.deleted_count, " documents deleted !!" ) |
Output:
1 documents deleted !!
