PyMongo is the module used for establishing a connection to the MongoDB using Python and perform all the operations like insertion, deletion, updating, etc. PyMongo is the recommended way to work with MongoDB and Python.

Note: For detailed information about Python and MongoDB visit MongoDB and Python. Let's begin with the Get Names of all Collections using PyMongo

Importing PyMongo Module: Import the PyMongo module using the command:

from pymongo import MongoClient

If MongoDB is already not installed on your machine you can refer to the guide: Guide to Install MongoDB with Python

Creating a Connection: Now we had already imported the module, its time to establish a connection to the MongoDB server, presumably which is running on localhost (host name) at port 27017 (port number).

client = MongoClient(‘localhost’, 27017)

Accessing the Database: Since the connection to the MongoDB server is established. We can now create or use the existing database.

mydatabase = client.name_of_the_database

In our case the name of the database is GeeksForGeeks

mydatabase = client.GeeksForGeeks

List the name of all the Collections in the Database: To list the name of all the collection in the database.

mydatabase.collection_names()

The collection_names() is deprecated in the version 3.7.0. Instead use

mydatabase.list_collection_names()

This method return the list of the collection names in the Database.

Example: Sample Database:

Python3 `

Python Program to demonstrate

List name of all collections using PyMongo

Importing required libraries

from pymongo import MongoClient

Connecting to MongoDB server

client = MongoClient('host_name', 'port_number')

client = MongoClient(‘localhost’, 27017)

Connecting to the database named

GeeksForGeeks

mydatabase = client.GeeksForGeeks

Getting the names of all the collections

in GeeksForGeeks Database.

collections = mydatabase.list_collection_names()

Printing the name of the collections to the console.

print(collections)

`

Output:

['Geeks']
