Python Decorators in 15 Minutes

Decorators are an advanced feature of the Python language that allow you to modify the behavior of a function or method without touching its code. This video will teach you why decorators work and how to create your own. It will also walk through a few examples to give you a better idea of where to use Python decorators.

Just to recap:

* Every value in Python is an object.
* Functions and classes are objects.
* Function definitions and class definitions are best thought of as special kinds of assignment statements, not as declarations; there are no declarations as such in Python.

Decorators work with classes as well, not just functions. Also worth adding:

* Every object is an instance of a class.

Note this also applies to classes, since they are objects.

I've read about decorators a dozen times. In books, tutorials, documentation of frameworks, etc. This is honestly the first time I actually understand the concept. Best explenation ever. Thanks Tim!

I looked so many videos, all of them were confusing. But this one just the perfect content I wanted. Thanks for this awesome video

the best ad for kites. have been seeing the ad everywhere but never wanted it. now i'm liking it

[RagingWhoremoans]

Wow this Kite AI thingy is really advanced, it does a darn good impersonation of that Tim fellow.

[garrenmiller]

Great explanation. I really appreciated that you gave a few concrete examples where decorators are useful instead of cutting off after explaining the functionality.

[kristiantorres]

The best explanation of decorators I've seen so far on youtube!

[Dtomper]

That log decorator is so powerful omg. Thank you for this amazing explanation <3

hey, it's Tech With Tim :O
I was legit surprised

[SovsemNeProstoy]

When I saw function decorators first time I thoght that it's the easiest theme that I've ever seen, but then I understood how useful and complicated they are. And now, I can say that this tutorial gave me the concept of decorators.

I really loved the way you explained about the decorators. 😊

I watched this video a year ago, created some decorator functions as snippets that I can use later. Now after a year I needed them so I used the snippets but honestly I forgot how they actually work but saved a link to your video. Watched this again and after 15 mins I understand everythingI need. I really appreciate your work Tim, I honestly think that there is absoutely nothing I could add or remove from your content like they go concisely from zero to a decent level of understanding in really short time.

I've had problems with decorators for a long time. This video finally solved it. Thanks ;)

I love how to the point this video is to the point. No fluff, you just start explaining. Reminds me of Miziziziz tutorials.

[soyaleye]

This is by far the most explanatory video for decorators I have seen on YouTube. It does not have the view count to match up to how helpful and insightful this video is.

[mikemace]

Absolutely the best, most concise tutorial on decorators - thank you!

[pawjast]

Hands down the best explanation of Python decorators in the whole YT!

[thomasdr]

Been trying to understand decorators, args, and kwargs for years. No clue how you were able to make this work so quickly and easily but I REALLY appreciate you!

Visualization really helps here. The f1(f) was what sparked my brain there

[ramonsantiago]

Tim explains things so well. If he made an advanced python course i would literally "shut up and take my money".
