Count documents in a collectionIn the video, you learned that a MongoDB database can consist of several collections. Collections, in turn, consist of documents, which store the data.You will be working with the Nobel laureates database which we have retrieved as nobel. The database has two collections, prizes and laureates. In the prizes collection, every document correspond to a single Nobel prize, and in the laureates collection - to a single Nobel laureate.Recall that you can access databases by name as attributes of the client, like client.my_database (a connected client is already provided to you as client). Similarly, collections can be accessed by name as attributes of databases (my_database.my_collection).Use the console on the right to compare the number of laureates and prizes using the .count_documents() method on a collection (don't forget to specify an empty filter document as the argument!), and pick a statement that is TRUE.

To count the number of documents in a collection in MongoDB, you need to use the .count_documents() method. Here's how you can do it step by step:

1. First, you need to connect to the MongoDB client. This is usually done using the pymongo library in Python. The connection could look something like this:

from pymongo import MongoClient
client = MongoClient('mongodb://localhost:27017/')

2. Once you're connected, you can access the database you want. In this case, we want the 'nobel' database. You can access it like this:

nobel_db = client.nobel

3. Now that you have the database, you can access the collections within it. The 'nobel' database has two collections: 'prizes' and 'laureates'. You can access them like this:

prizes_collection = nobel_db.prizes
laureates_collection = nobel_db.laureates

4. Finally, you can count the number of documents in each collection using the .count_documents() method. You need to pass an empty filter document as the argument to count all documents. Here's how you can do it:

prizes_count = prizes_collection.count_documents({})
laureates_count = laureates_collection.count_documents({})

5. Now you have the count of documents in both collections. You can print them out or use them in your code as needed.

Remember to replace 'localhost' and '27017' with your MongoDB server's IP address and port if you're not running the server locally.
