How to Store and Retrieve Data using Python, SQLite and SQLAlchemy

Data Management with Python, SQLite and SQLAlchemy, you'll learn how to store and retrieve data using Python, SQLite, and SQLAlchemy. Python, SQLite, and SQLAlchemy give your programs database functionality, allowing you to store data in a single file without the need for a database server.

In this tutorial, you'll learn how to store and retrieve data using Python, SQLite, and SQLAlchemy as well as with flat files. Using SQLite with Python brings with it the additional benefit of accessing data with SQL. By adding SQLAlchemy, you can work with data in terms of objects and methods.

All programs process data in one form or another, and many need to be able to save and retrieve that data from one invocation to the next. Python, SQLite, and SQLAlchemy give your programs database functionality, allowing you to store data in a single file without the need for a database server.

You can achieve similar results using flat files in any number of formats, including CSV, JSON, XML, and even custom formats. Flat files are often human-readable text files—though they can also be binary data—with a structure that can be parsed by a computer program. Below, you’ll explore using SQL databases and flat files for data storage and manipulation and learn how to decide which approach is right for your program.

In this tutorial, you’ll learn how to use:

  • Flat files for data storage
  • SQL to improve access to persistent data
  • SQLite for data storage
  • SQLAlchemy to work with data as Python objects
