Python Development Track
Python is one of the most popular programming languages in the world, and one of the easiest to start with. Companies use it for web applications, automation, data work and AI tools, so it's a good first language for anyone who wants to work in tech.
This track follows the full Python Development curriculum. You'll start with the basics: variables, loops, conditionals and functions, the building blocks you'll use in every Python program. You'll use them to build small command line programs, like a number guessing game.
Next, you'll learn to work with data. You'll use lists, dictionaries and other Python data types to clean up messy data and organize it. Then you'll learn object-oriented programming (OOP), where you design your own classes to model how a program behaves.
After that, you'll connect your code to databases. You'll read and write CSV files, store and query records with SQLAlchemy, and build a web application with a database behind it. Along the way, you'll practice testing your code, working with APIs and deploying your projects.
Finally, you'll learn to use AI tools like a working developer does. You'll prompt an AI coding assistant, debug the code it writes and improve it, and you'll learn when to trust its output and when to question it.
By the end, you'll be able to plan and build complete Python applications on your own, from simple scripts to web apps that use a database.
