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
Decorating Functions With Variable Arity
Preserving Metadata of Decorated Functions
But that's not all! Each concept will be reinforced through engaging coding assignments of increasing difficulty. Throughout the course, will also explore several skill challenges inspired by real-world scenarios including:
Logging Function Output
Timing Runtime Performance
Using Decorators In Mocked Authentication Flows
Creating Cache Mechanisms
This course is tailored specifically for Python programmers interested in deepening their understanding of decorators as a gateway to functional programming or as a standalone, intermediate-level programming pattern.

Instructor
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.
