Python Working With Mongodb Tutorial – Complete Guide

Building a strong backend for any application can make or break the functionality and overall success of your project. One of the popular solutions used today involves Python and MongoDB; a potent programming cocktail that serves a splendid blend of scalability, flexibility and ease of use. This powerful combination is increasingly being employed by developers to create dynamic web applications, games and much more.

What is Python?

Python is a high-level programming language that is recognized for its simplicity and readability. Its syntax generally allows programmers to code complex functionality with fewer lines than most other languages. An added bonus is that Python comes with a vast ecosystem brimming with softwares, libraries and frameworks that extends its capabilities.

What is MongoDB?

MongoDB is a database program that is used by developers around the world. It features a document-oriented NoSQL database to structure data in a flexible, JSON-like format, making it versatile in handling various types of data.

The Bond between Python and MongoDB

Python, due to its power and simplicity, combined with MongoDB’s flexible database structure results in an incredibly strong backend solution. This fusion serves to be useful in a multitude of applications such as game development, where the real-time processing of vast amounts of data is essential.

If you’re aiming to build dynamic, scalable and efficient applications or games, then Python and MongoDB is the skillset you need. Not only does it enhance your overall coding prowess, but it also makes you a valuable assert in the growing world of digital development.

Setting Up Your Environment

Before proceeding, you’ll need to ensure both Python and MongoDB are installed on your machine. You can download MongoDB here and Python here if not already installed.

Installing the Necessary Package

To connect to our MongoDB database from Python, we’ll have to install the pymongo package. Install the package using the pip installer as follows:

pip install pymongo

Establishing a Connection

Now that pymongo is installed, we’ll create a connection to our MongoDB server. Use the following lines of code to connect:

from pymongo import MongoClient
client = MongoClient("localhost", 27017)

The above code will connect to MongoDB running locally on port 27017.

Creating a Database

Once we’re connected, we can create a new database in MongoDB. Let’s create a database called ‘gamedb’ using the following line of code:

db = client['gamedb']

Creating a Collection

A ‘Collection’ in MongoDB is similar to a ‘Table’ in traditional relational databases. Create a collection using:

collection = db['gamecollection']

Inserting Documents

Let’s insert a simple document into our newly created collection. A document is akin to a ‘record’ in traditional databases and is essentially a group of key-value pairs.

doc = {'name': 'Super Mario', 'genre': 'Platform', 'year': 1985}

Retrieving Documents

We can retrieve our newly-inserted document using a simple find query as follows:

result = collection.find({})
for i in result:

Querying Documents

In MongoDB, we can query data using various conditions. For instance, if we want to find games released after a certain year:

query = {"year": {"$gt": 2000}}
for game in collection.find(query):

This code will print out all games in our collection that were released after the year 2000.

Updating Documents

We can also update existing documents in our collection. Let’s modify the year of ‘Super Mario’ to 1987:

query = {"name": "Super Mario"}
update = {"$set": {"year": 1987}}
collection.update_one(query, update)

After executing this code, the year for ‘Super Mario’ in our database will be updated to 1987.

Deleting Documents

To delete a document from the collection, you can use the delete_one or delete_many method. Let’s remove ‘Super Mario’ from our collection:

query = {"name": "Super Mario"}

After running this command, the ‘Super Mario’ document will be deleted from our collection.

Counting Documents

If you’d like to know the number of documents in your collection, you can use the count_documents() function. Here’s how to use it:

count = collection.count_documents({})
print(f'Total documents in gamecollection: {count}')

This command prints the total number of documents in our ‘gamecollection’.
