    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.

      ditto. I was starting to wonder if it it was me being slow trying to understand how decorators work.

    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!

    How beautifully and brilliantly explained,
    First show the necessity, then explain the solution provided by the CONCEPT.

    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

  • @cgabt1109
    @cgabt1109 7 ปีที่แล้ว +2

    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.

    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)?

    @muhammadasifsaeed500 3 ปีที่แล้ว

    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

    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
