How to Retrieve a Document for a Specific Timestamp in MongoDB Using pyMongo

MongoDB is a powerful NoSQL database that allows you to store a variety of data types in a flexible format. Whether you're building a web application or managing large datasets, you might encounter situations where you need to retrieve documents based on specific criteria, such as a timestamp. In this guide, we will discuss how to retrieve a document with a specific timestamp using the pyMongo client. Let's dive in!
