Decorators - Advanced Python Tutorial #2

[@deei5130]

This channel is easily one of the best python tutorial channels there are, if not the best one

[@SparePlayss]

Hence proved.. KZbin's Recommendation is faster than KZbin's Notification

@@destiny_02 Lmao KZbin go brrr

[@ronakshah3891]

Can we have multiple decorators declared for a single function. For example, logging the result and calculating the time.

[@tomasgorda]

great video again, thank you very much. What environment do you using ? It looks like vi with some staff around (files structure, compilator etc.) I'm using sublime text with kite for example. Thanx a lot for your answer.

[@harrybestfriend5282]

its neovim i think with a custom theme,

[@tomasgorda]

@@harrybestfriend5282 ok thank you very much 👍

[@harrymagooslum5770]

Yours was the only KZbin explanation of Decorators in Python that actually demonstrated the practical use. I thank you greatly for that because the lightbulb turned on brightly as a result. You did a really nice job of it and I look forward to checking out other instructional videos that you make.

[@ismahenelarbi7386]

I also recommend key2learn's videos about closures :)

[@lxathu]

And the only (or at least the first) one I've seen that doesn't leave the viewer alone with the question if calling the wrapper explicitly or by the decorating syntax are the same.

[@renxooo5962]

i always get hyped up but instantly get lazy when ima bout to code

[@NeuralNine]

Push through it you will be happy afterwards :)

def decorater(fun): def wrsper(): print("wraper fun") hello() return wrsper() def hello(): print("main function") decorater(hello)() error wraper fun main function Traceback (most recent call last): File "E:\learn\youtube.py", line 11, in decorater(hello)() TypeError: 'NoneType' object is not callable

[@Alexander-dj1jp]

in your function you take "fun" as an argument, but then you try to call "hello" inside that function, you would need to call "fun" because that was your argument "hello" isn't defined inside "decorator" function, that's why you get the error.

[@alex_mahone]

The timing of this lesson is perfect! I actually have to go over a script that uses pytest and a lot of decorators with one of our engineers with not a lot of coding background tomorrow. This lesson makes explaining a lot easier! Thank you!

[@skrinkz8201]

I haven't seen a notification nor seen an update for any of your videos in my feed for the last probably 3-4 weeks O.O

[@NeuralNine]

click the bell ^^

[@arihannnt]

Just a quick query! What if we do something recursive in the function for instance I tried timing how long does it take to execute a factorial function! The recursive implementation kinda went haywire. Would love to know if there's a clean way to handle that

[@WZNuget]

Note: doing decorator(function)() wont work on python 3.9 it will throw you a type error instead just do decorator(thefunction) it will call the wrapper automatically edit: if your returning the function you can use the functobecalled(function)() thing

[@cytolytic]

you must do a video on your vim config

[@NeuralNine]

I will :)

[@cytolytic]

@@NeuralNine thanks :D

[@TestingQuantumSoftware]

I like that you don't spend time on bs. You go direct to the point, have a clear explanations, good examples and overall great content! congrats!

[@YerNar-g6t]

thank you very much brother!!!!! lovely videos pls dont stop, wish you all the best! cause you r the best!!!!!!!!!!!!!

[@mj2068]

fun observation: the reason why the number of calculations increased from 10k to 90k, i.e. 9 folds. but the time they took increased by over 220 times(0.025 to 5.6) is because factorial is not linear.🤯

[@TheCodingBug]

Great series! and it would really come in handy if someone is planning to implement custom layers for TensorFlow or Keras. I remember back in the day, I was trying to implement a custom layer for F1-score and it really took me a long time to figure out how to use these hidden functions of Python. It's great to see such a thought through video on the topic!

[@pranav6957]

I always try these programming and these programs works.thanks for these best programming video to make us a best programmer. :) Love from india.😊😊

[@jsmyers24151]

The result of the code at 8:40 gave me a printout of "None" at the bottom. I used ChatGPT to tell me what was going wrong with that. It came back that I needed to remove the last "print" command at print(hello("Jeff")). I did, and "None" was no longer there. I also ditched the outer parentheses.

[@arandomwho]

Pretty much simple and practiacl, thanks for your awesome work!

[@pankrecik]

@NeuralNine to make it easier to record and watch video you could execute and preview results of the script your are working on directly from vim using shortcut

[@robinferizi9073]

I finally understand, thank you dude

[@123arskas]

Time decorator was beautiful example. Will use it everywhere.

[@asifabrar5892]

Hey​ @NeuralNine, I love to watch your videos and try to use these lessons in my projects. I have a question about decorators. Can I use same decorator for multiple functions? like: def timed(function): ... def chd_func(): ... def chd_func_2(): ... def func(): if 1: chd_func() elif 2: chd_func_2() Here I want to use "timed" decorator for chd_func() and chd_func_2(). If I use the decorator for both child functions, the first child function always executes first. But I want to execute the func() first. What should I do?

[@thirumala_reddy]

Good explanation
