How to Connect to Mongodb with Python in 2025?

As we step into 2025, connecting to MongoDB using Python remains a vital skill for developers. MongoDB’s flexibility as a NoSQL database and Python's simplicity make them a powerful duo for modern application development. In this article, we will guide you through connecting Python applications to a MongoDB instance effectively.

Prerequisites

Before diving in, ensure you have the following:

  • Python 3.10 or above installed on your machine
  • Access to a MongoDB instance (locally or via a cloud service)
  • Familiarity with basic Python programming

Step 1: Install Necessary Packages

First, start by installing the pymongo package, which is the official MongoDB driver for Python. If you haven't already, you can install it using pip:

pip install pymongo
Enter fullscreen mode Exit fullscreen mode

Step 2: Establish a Connection

Once you have pymongo installed, you can create a connection to your MongoDB instance. Here’s a simple example of how to do this:

from pymongo import MongoClient


client = MongoClient('mongodb://localhost:27017/')


db = client.your_database_name

print("Connected to MongoDB!")
Enter fullscreen mode Exit fullscreen mode

In this example, replace 'mongodb://localhost:27017/' with your MongoDB URI. This connection string might point to your own server or a cloud-based MongoDB Atlas instance.

Step 3: Performing Basic Operations

Now that you have a connection to the database, you can start performing CRUD (Create, Read, Update, Delete) operations.

Inserting Documents

Use the insert_one() or insert_many() methods to add documents to a collection:

collection = db.your_collection_name

new_document = {"name": "Alice", "age": 30}
result = collection.insert_one(new_document)

print(f"Insertion ID: {result.inserted_id}")
Enter fullscreen mode Exit fullscreen mode

Reading Documents

Read or query documents using find_one() or find() methods:

document = collection.find_one({"name": "Alice"})
print(document)
Enter fullscreen mode Exit fullscreen mode

For advanced querying techniques like finding specific sub-documents, refer to this guide on querying specific sub-documents in MongoDB.

Updating Documents

Update documents using the update_one() or update_many() methods:

collection.update_one({"name": "Alice"}, {"$set": {"age": 31}})
Enter fullscreen mode Exit fullscreen mode

Understanding the update method is crucial; check out this resource on MongoDB update syntax for more details.

Deleting Documents

Remove documents using delete_one() or delete_many():

collection.delete_one({"name": "Alice"})
Enter fullscreen mode Exit fullscreen mode

Advanced Usage

For those dealing with JSON data, MongoDB’s support for JSON-like documents is robust. To master searching for specific values in JSON objects within MongoDB, take a look at this JSON object search guide.

Conclusion

Connecting to MongoDB with Python in 2025 is straightforward with pymongo. By following these steps, you can efficiently manage your MongoDB databases and leverage Python’s capabilities for data manipulation and analysis. Whether you are developing small-scale applications or handling large datasets, mastering the integration between these two powerful technologies will undoubtedly enhance your software development skills.

By keeping your knowledge up-to-date, such as understanding advanced MongoDB queries and operations, you'll ensure your applications remain performant and adaptive to the latest advancements in technology.
