The way you've explained this topic is truly impressive.

[@EyadKotb-zf5tf]

You are literally theeee best , now and only I can understand decorators ,I absolutely love your approach of explaining things slowly with pure logic .keep it up!!!!

[@durandas6661]

The way you describe concepts it's soo easy too understand, really appreciate your works...

[@sachinnerkar9629]

This is really a master piece . I never visualized the actual flow of decorator anywhere. Thank you very much.

[@starshipx1282]

Best explanation I ve come across ...

[@MrMukulpandey]

Great...keep doing this...your explanation is really great.....u have cleared my OOPs concepts very clearly ❤️

[@alvarocubi]

Thank you for another great tutorial!

[@michaelmueller9635]

Dude, you are describing it so well and brilliant ...that it's really hard and difficult not to understand it 👍

[@lordmahakaal]

For the first time in my life I got to understand decorators cuz of you sir. Thanks a lot

[@FitnessChaos]

Finally a good video on decorators

[@Chaplainelmo2001]

Very logically presented from a senior hobbyist.

[@fizipcfx]

woow i always wondered how decorators can accept parameters, now i got it. i think even procedurally generated decorators are possible

[@ygcjayalal]

excellent lesson, very simple and easy to understand. Thank you so much

[@turtlecode]

Perfect Tutorial. Thanks

[@sonu-jangir]

Once again, It's a great video on this channel.🎉❤

[@csd4ni3l]

yeyyy new video

[@juicedelemon]

wow! that is a lot of tutorials in a month!

[@YassFreeks]

I didn't finish the last video yet, I can't keep up the pace 😫 😪 But thank you so much for this content ❤️

[@horaciormartinez1551]

Pythontutor is a good help to follow this video

[@EMRAN994]

great explanation

[@atharvahode5553]

Thanks great video.

[@M.I.S]

very GOOD!

[@kyngk]

Can you make a video about async programming with asyncio/await syntax?

[@pranavnyavanandi9710]

It would be great if you could make a video on the descriptor protocol. Much of how Python works behind the scenes is based on or has something to do with descriptors. I have tried to understand them from many sources but still have not.

[@terraflops]

I went with Star Trek theme for decorators def replicator(function): def food(food_params): print(" replicator() -> food() ") function(food_params) print(" food replicated ") return food @replicator def mealtime(func_params): print(func_params) mealtime("sandwich")

[@pranavnyavanandi9710]

A decorator is a higher order function that utilizes the property of closures, and helps dynamically add functionality to a function without altering any of it's own functionality. Learnt this from the great youtuber Corey Schafer.

[@Yassinius]

I've been programming python for 3.5 years and for the time being I got away with never using decorator. Every time I saw someone use decorators it confused me so much. Thanks for explaining a concept that seemed so daunting and making it actually easy :) It's really helpful

[@GreenlackX]

I See That I Have Bin Coding Now 1.8 Years Of My Life (Python), This Was Really Helpful.

[@captain_vegan]

same i've been programming for 3 years n i never used decorators

[@pranavnyavanandi9710]

Well try understanding properties and descriptors then. There's something called a descriptor protocol that is very related to how python works internally.

[@ankitaswal2894]

Wow

[@fouezdesign]

Absolute mind torture.

[@akshatsingh3458]

😂😂😂😂

[@pranavnyavanandi9710]

Watch the video by Corey Schafer in his Python OOPS Playlist. That's how I got started with it all. Pretty simple concept once you get the hang of it.

[@fouezdesign]

@@pranavnyavanandi9710 you're right, with all respect to this guy but no one beats Corey.

[@shinobi1975]

18:31 why didn’t it print “Function” twice??? func() was called once in decorator and duration_decorator wrapper function. Can somebody explain this.

[@omerfidan892]

if you can make the examples with numbers like, func1 func2, every where you write same name and we strugle to understand whch is what.

[@el_munoz]

Thats a very good explanation about Decorators, but in the class example you forget to change the "self._x" in the __init__ method for "self.x" for avoid self reference.

[@nursing_father738]

Nice explanation. but when I run the same code it gives a type error.. Nonetype error is not callable

[@nursing_father738]

i fixed it

[@ilanlee3025]

Started off well and your explanation is good but the written example is bad and confusing. You should have not named everything func. It is just confusing. You should have named it something else or no one can understand what is the use case. I can delete half this code and func() will still print out the function output.
