Yours was the only YouTube 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.

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!

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!

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

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!

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):

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.🤯
