Using MongoDB with Python

Introduction to using MongoDB with Python

Python is a popular programming language that can be used to interact with MongoDB databases. The pymongo library provides tools to connect to MongoDB, perform CRUD operations, and manage your database effectively.

Installing PyMongo

To use MongoDB with Python, you need to install the pymongo library. You can install it using pip:

pip install pymongo

Connecting to MongoDB

After installing pymongo, you can connect to your MongoDB server using the following code:

from pymongo import MongoClient

client = MongoClient("mongodb://localhost:27017/")
db = client.myDatabase

CRUD Operations

You can perform CRUD (Create, Read, Update, Delete) operations using pymongo. Here are some examples:

collection = db.myCollection
document = {"name": "Alice", "age": 25}
collection.insert_one(document)

result = collection.find_one({"name": "Alice"})
print(result)

collection.update_one({"name": "Alice"}, {"$set": {"age": 26}})

collection.delete_one({"name": "Alice"})
