Python and SQL for Beginners

Learn to connect Python with real-world data—fast.

Python & SQL for Beginners is the complete guide to combining two of the most in-demand skills in tech: programming with Python and managing data with SQL. This book walks you through the essentials of building data-driven Python applications using SQLite, MySQL, and PostgreSQL—even if you’ve never worked with a database before.

You’ll start by learning the basics of SQL: creating tables, inserting data, and writing queries. Then, you’ll move into Python and learn how to integrate both using libraries like sqlite3, SQLAlchemy, and psycopg2.

Inside, you’ll discover how to:

• Understand relational databases and how they work

• Set up and manage your own SQLite, MySQL, or PostgreSQL databases

• Connect to databases from your Python applications

• Create, read, update, and delete data with SQL commands

• Build simple CRUD apps from scratch

• Handle errors, transactions, and security best practices

• Use SQLAlchemy ORM to write cleaner, scalable database code

• Generate reports, build dashboards, or power backend web apps

Each chapter includes code examples, hands-on exercises, and practical use cases. Whether you're working on your first portfolio project or building tools for work, this book gives you the skills to integrate Python and databases with confidence.
