MongoDB is an open source NoSQL database that provides high performance, high availability and easy scalability. It works with the concept of collections and documents, unlike traditional relational databases that use the concept of tables and records. MongoDB is a document-oriented database, which means it stores its data in BSON documents (a binary representation of JSON) with a dynamic schema.
On the other hand, Python is a high-level, interpreted, scripting, imperative, object-oriented, functional, dynamically typed, and strong programming language. Due to its clear and readable syntax, Python has been one of the most popular programming languages for manipulating data. The combination of Python and MongoDB can provide a complete solution to many data manipulation problems.
Python has a library called 'PyMongo' that allows your Python code to communicate with the MongoDB database. PyMongo contains tools that help communicate between Python and MongoDB. With PyMongo, you can create a connection to the MongoDB server, create a database, create a collection, insert documents into the collection, update documents in the collection, query documents in the collection, and delete documents in the collection.
To start using MongoDB with Python, you first need to install MongoDB on your machine and start the MongoDB server. Next, you need to install the PyMongo library in your Python environment. This can be easily done using Python's pip package manager with the command 'pip install pymongo'.
Once you have the MongoDB server running and the PyMongo library installed, you can start writing your Python code to interact with the MongoDB database. The first step is to create a connection to the MongoDB server. This can be done using the MongoClient function from the PyMongo library.

After establishing a connection to the MongoDB server, you can create a database. In MongoDB, a database is not created until it is "actually" populated. In other words, MongoDB creates a database only when you save some data to it.
After creating a database, you can create a collection. A collection in MongoDB is the same as a table in SQL databases. A collection is used to store documents.
Once you have a collection, you can start inserting documents into it. A document in MongoDB is the same as a record in SQL databases. A document is a set of key-value pairs. Keys are strings and values can be many different data types, such as strings, numbers, lists, other documents, and so on.
In addition to inserting documents into a collection, you can also update documents in a collection, query documents in a collection, and delete documents from a collection. PyMongo provides several functions to perform these operations.
In summary, the combination of MongoDB and Python can be a powerful tool for data manipulation. With MongoDB, you get a high-performance NoSQL database, while with Python, you get a high-level, easy-to-use programming language. The PyMongo library makes communication between Python and MongoDB simple and efficient.
