Connecting Python to Databases

Databases are essential for storing and retrieving data in web applications. Python provides libraries like sqlite3, SQLAlchemy, and PyMySQL to connect and interact with databases.

In this lesson, you’ll learn how to connect Python to a database and perform basic CRUD (Create, Read, Update, Delete) operations.

Using SQLite with Python

SQLite is a lightweight, file-based database that comes bundled with Python. It’s ideal for small applications or testing purposes.

# Connecting to SQLite
import sqlite3

conn = sqlite3.connect('example.db')  # Creates or connects to a database file
print("Connected to SQLite")
