Download this code from https://codegive.com
Creating a MongoDB database using Python is a common task in application development. MongoDB is a NoSQL database that stores data in a flexible, JSON-like format, making it suitable for a wide range of applications. In this tutorial, I will guide you through the process of creating a MongoDB database using Python, and I'll provide code examples to help you get started.
Before we begin, make sure you have the following installed:
Python: Ensure you have Python installed on your system. You can download and install it from the official Python website.
MongoDB: You need to have MongoDB installed and running. You can download MongoDB from the official website.
PyMongo: PyMongo is a Python driver for MongoDB. You can install it using pip:
To interact with MongoDB using Python, you need to import the PyMongo library. Create a Python script and import the library:
Now, you need to establish a connection to your MongoDB server. Replace YourMongoDBURI with your MongoDB connection URI. You can find your URI in your MongoDB Atlas account if you're using Atlas or set it according to your local MongoDB installation.
To create a database, you can use the following code snippet. Replace YourDatabaseName with the name you want to give to your database:
In MongoDB, data is stored in collections. You can think of collections as equivalent to tables in relational databases. To create a collection, you can use the following code. Replace YourCollectionName with the name you want to give to your collection:
You can insert data into your collection using the insert_one() or insert_many() method. Here's an example of inserting a single document into your collection:
You can also insert multiple documents at once using insert_many():
You can query the data in your collection using various methods provided by PyMongo. Here's an example of how to query all documents in a collection:
You can also query based on specific criteria, sort the results, and much more. Refer to the PyMongo documentation for advanced querying options.
After you've finished working with your MongoDB database, it's a good practice to close the connection:
That's it! You've successfully created a MongoDB database and interacted with it using Python. MongoDB provides many advanced features for data manipulation, so make sure to explore the documentation to utilize its full potential.
