MongoDB with Python: CRUD Operations Tutorial

Insert and Query Users

Write a Python script to insert three user documents into a MongoDB collection and then query all users older than 20.

Expected output: Printed user documents with age greater than 20.

Hint: Use insert_many() for insertion and find() with a filter for querying.

Update User Email

Create a Python script that updates the email address of a user named 'Bob' in the MongoDB collection.

Expected output: Confirmation of matched and modified document counts.

Hint: Use update_one() with a filter on the name field and $set to update the email.

Delete Users by Age

Write a script to delete all users younger than 18 from the collection.

Expected output: Number of deleted documents printed.

Hint: Use delete_many() with an age filter less than 18.

PyMongo is the official Python driver for MongoDB. It is used to connect Python applications to MongoDB databases and perform CRUD operations.

You use the update_one() method with the $set operator to update a specific field without replacing the entire document.

You use the insert_many() method to insert multiple documents into a collection in one operation.
