Description
Welcome to the best and most complete guide to Python decorators!
In this course, you will cultivate a deep and practical understanding of decorators in Python, starting from the very basics. This beginner-friendly course is meticulously crafted to ensure you build a solid foundation from scratch while also getting ample practice in the process.
Before diving into decorators, we'll explore the fundamental principles that serve as the building blocks of this intriguing topic. You'll gain a deep understanding of higher-order functions, closures, and first-class functions – prerequisites that unlock the magic of decorators. Foundational topics include:
Closures
First-Class Functions
Variadics
Higher Order Functions
Once we have established a solid grasp of these functional foundations, we'll dive into the captivating world of decorators. We'll start with a gentle introduction and gradually move towards more intricate techniques. Our exploration of decorators will include:
Basic Decorators
Decorating Parameterized Functions
Chaining Decorators

Hi! I'm Andy, a freelance software developer and capital markets consultant based in Toronto, Ontario. I've spent close to a decade working with data, using code to automate business workflows, and consulting financial institutions on data-intensive applications.
Although I'm comfortable in a number of programming languages, for me nothing beats python on a ROIE (return on invested effort) basis. It is my go-to language in my consulting work and also my focus here on Udemy.
Aside from teaching, I specialize in consulting financial institutions in post-trade services technology.
