Python Decorators 101

Christopher Bailey

In this course on Python decorators, you’ll learn what they are and how to create and use them. Decorators provide a simple syntax for calling higher-order functions in Python. By definition, a decorator is a function that takes another function and extends the behavior of the latter function without explicitly modifying it.

Incredible course - very well thought out and designed. The best RealPython course I’ve done so far (and I’ve done quite a lot!)

The best thing about this course is how much groundwork the teacher laid first, to avoid blowing our brains up when explaining decorators, a topic which most people find quite hard to grasp.

The design of this course shows a huge amount of thought about which aspects of decorators are the sticking point for most newbies, and how convey understanding about the precursor elements that make decorators easier to understand.

I was pleasantly surprised at how relevant and useful the examples were. I liked that the text-entry screen caps are sped up so that we’re not sitting there watching someone type slowly.

Fantastic work, RP team!

This lesson was great for me. It connects multiple loose ends and gives the experience of closure. I will be playing around with this some more in the coming weeks. I always want slow speekers: Christopher speaks way too fast for me, but it is just about perfect at speed 0.75.

Thanks a lot for this one. Do not throw it away ever. It might me an older video, but I think it has great value.

Really liked this class. It was a slow and methodical exposition on a difficult topic. I’ll probably review the class a few more times for it all to sink in. Thanks Chris!!!

I was working through a tutorial on OOP, and decorators were mentioned. Not being very confident that I knew what they were, I found myself here, and I’ve learned a huge amount already. Excellent course, Christopher - thank you.

The video version of this tutorial was much better for me than the written one, which to me just seemed like an exercise to go through. I found the real world examples almost riveting and have them safely saved away!

Thanks for the awesome tutorial on Decorators. If I had to study decorators for an interview this would be my one stop shop for decorators starting right from the Beginner
