Connect to MongoDB from Python Application – Example

Connect to MongoDB from Python

Connect to MongoDB from Python – In this MongoDB Tutorial, we shall learn to connect to MongoDB from Python Application.

To connect to MongoDB from Python Application, follow the below step by step guide :

1. Install Python Driver – PyMongo

   PyMongo contains tools for working with MongoDB.
   To install PyMongo in Linux/OS X, use pip as shown below :

   pip installpymongo

   Terminal

   root@tutorialkart:/home/arjun# pip install pymongo Collecting pymongo Downloading pymongo-3.5.1-cp27-cp27mu-manylinux1_x86_64.whl (368kB) 100% |????????????????????????????????| 368kB 13kB/s Installing collected packages: pymongo Successfully installed pymongo-3.5.1

   To install PyMongo on Windows, use installer at https://pypi.python.org/pypi/pymongo/.

2. Import MongoClient from pymongo

   In you Python Script, import MongoClient that acts as a Client from Python to MongoDB.

   from pymongo import MongoClient

   1 2 3

   from pymongo import MongoClient

3. Create a connection to MongoDB Daemon Service using MongoClient

   Following is the syntax to create a MongoClient in Python

   client = MongoClient(URI);

   1 2 3

   client = MongoClient(URI);

   URI is where the MongoDB instance runs.
   Example : mongodb://192.168.1.154:27017
   Note : If URI is not specified, it tries to connect to MongoDB instance at localhost on port 27017.

4. MongoClient is Ready

   If there is no exception thrown during MongoClient creation, your MongoClient is successfully connected to MongoDB.

5. Close connection to MongoDB

   Once you are done with the MongoDB Operations, close the connection between MongoClient and MongoDB Daemon Service.

   client.close();

   1 2 3

   client.close();

Following is an example Python Script to demonstrate on how to establish a connection to MongoDB from Python by creating a MongoClient :

 

Conclusion :

In this MongoDB Tutorial, we have learnt to make a connection to MongoDB from Python using PyMongo Driver.
