I've been watching native English speakers all day.. couldn't understand this concept. I find this guy who has a thick accent and I understand his lesson perfectly. This guy is truly talented. Subscribed.
You are a very rare type of person that has an ability to do what not many programmers can which is to be able to explain code so anyone can understand it. You have a gift. I wish you all the success possible. Brilliant explanation!
Sir am really humbled, decorators have been a nightmare to me for about an year, as a self taught, just today I have been able to understand and fix this issue. sir be Blessed.
fantastically explained bloody fantastic sooo many youtubers have tried explaining decorators but none has come close to how you explained the use, the reason why we use this, what benefits and examples of when to use it. you sir are dime in a dozen, be proud you are very good perfect way to explain stuff and you were original as some youtubers have been copying of each others when making videos on decorators you can tell by the same code examples they keep using but you sir are unique, congrats
Your tutorials actually made me realise the importance of different programming styles; it has made me understand how things are connected in the world of computers. I was always thinking about syntax and semantics most of the time. Thank you for your Help.
Wow...Well explained.. I had put lots of effort to understand decorator but couldn't. Thanks to your tutorial for simplifying the concept. Great Job !!!
Thanks so much for this video. I am taking a Python 3 essentials course on Lynda.com which is pretty good but the decorators lesson was a complete let down. I've tried a number of articles on the web before landing on yours which is true gem. Your choice of measuring time as a decorator function makes perfect sense and I wish others used it too. Even your runtime "error" when before you inserted @time_it, shows exactly what that statement does. Can't thank you enough. btw, subscribed.
Very well explained.. I'm taking a course in udemy on Python, but couldn't able to understand this topic , but your explanation is way better . Thanks !
Dude.. I have seen a lots of videos.. not clearly understood.. but you made me understood..thanks a lot.. please make a video on asymptotic notation.. it would be helpful for many..

Hi, when exactly time_it() return wrapper? instead of doing this things: # out_square = calc_square(array) # out_cube = calc_cube(array) # print type(out_cube) if we are using @time_it, why cant we directly call calc_square(array)?
I have learned, decorator takes the function as an argument. And that function should not get any argument. But in your case, your decorator time_it is taking function (calculate_square) and function (calculate_square) is also getting argument numbers. I think its against the def of decorator. Could you please guide me. Thank you
Thank you for nice explanation. which is this platform on which you are running Python code, could you please also make a video about how to debug the program using this platform.
Thanks for the explanation but just a question why did you pass **kwargs parameters used are array(list/tuple) only and I don't see any dictionary over there so **kwargs is not needed I guess. Please clarify this

ditto. I was starting to wonder if it it was me being slow trying to understand how decorators work.
Not exactly a compliment

How beautifully and brilliantly explained,
First show the necessity, then explain the solution provided by the CONCEPT.
Very good Job.
Sir, I can't fully express my gratitude to you for breaking down such a complex concept in such a comprehendable way!
You are very good in explaining a confusing concept in easy to understand language.. thank you very much
Very true. Great!

👍☺️
Not only was this a good explanation, but the example was exactly what I was trying to use decorators for. Thank you.

Damn. That was just too good. Watched so many decorators tutorial and videos and none went into my head. This was magic.
Akshay, I am happy it was useful to you :)

You made it easy to understand, whereas others almost seems to want to make it more complicated than it has to be.
Justin thanks for the feedback buddy 👍
I had seen alot videos on decorators in last few years but it is simplest explanation of decorators I have found.
Foss in, thanks for your feedback

very well described...thanks!
Good explanation with a catchy example..
Excellent. Very good explanation
Nice Explanation good keep it up
Glad you liked it Shivam
I don't understand.Why we need to put *args and **kwargs in wrapper?why should the wrapper function take positional arguments?
This was a very good tutorial.
Can we add two different decorators in a function? One for logging and one for time.
A function definition may be wrapped by one or more decorator expressions

Great tutorial i really like u started with why we need it with awesome example
Good tutorial with debugging.. !!
Brilliant explanation, thank you
Thank you , explained very good
Thank you so much sir. Well Explained . Which software you are using for python ???
Thanks.
Understand the use case.
Hi,
when exactly time_it() return wrapper?
instead of doing this things:
# out_square = calc_square(array)
# out_cube = calc_cube(array)
# print type(out_cube)
if we are using @time_it, why cant we directly call calc_square(array)?
Sir could you please tell me what does it mean by
array=range (1,100000)
I couldn't get it...
Brilliant Explanation.
Thanks for this video.
Adam I am glad you liked it 😊
Thank you. It's very clear
Dude great job
Glad you liked it yiyan 😊👍
Good explanation
Thank you so much for this video!
Very good example
Very well explained, may I know tool/software which you are using here
camtasia studio by tech smith
Very clear.. Thank you
Can you give more details on why the return statements are necessary in the decorator please? I can’t find a good explanation anywhere.
What's the use of return wrapper line?
where we can use '@' in the program?
how it can define that the function Is decorator in the above example?
Very helpfull thank you!
Thank you. It is understandable.
I have learned, decorator takes the function as an argument. And that function should not get any argument. But in your case, your decorator time_it is taking function (calculate_square) and function (calculate_square) is also getting argument numbers. I think its against the def of decorator. Could you please guide me. Thank you
Which is executed first decorator or python script
Is there any way to decorate a function that you imported e.g. with the time_it?
Sir is it not possible to achieve this by inheritance concept???
Please make a tutorial video on "arrow" module..
Thanks a lot Sir
Thank you for nice explanation. which is this platform on which you are running Python code, could you please also make a video about how to debug the program using this platform.
Thanks for making this easy. Can you please explain, how decorators are used in Web development.
Thanks for the explanation but just a question why did you pass **kwargs parameters used are array(list/tuple) only and I don't see any dictionary over there so **kwargs is not needed I guess. Please clarify this
