Colton Myers: Decorators: A Powerful Weapon in your Python Arsenal - PyCon 2014

[@PixelOutlaw]

Good overview of using Python in a relatively powerful yet little used way. This video echoes the intention of dynamic programming conceptually presented in the SICP videos from MIT. Very enjoyable.

great explanation

[@736939]

I didn't understood at 19:34 how did he counted the function calls - first, he calculates +=1 and then update to 0, so initialization of counter should be done After ??? :(

[@babuarthimalla678]

nice explaination

[@siddhantloya9587]

why do you return ret at 8:44 . since it is only None

[@asdfasdfuhf]

In the example he showed, you are correct it wasnt necessary; but if the function would have returned some value, it would have been necessary. So basically, it doesn't do anything.. yeah. Edit: he actually also said it it at: 11:33

[@CSryand2m]

What is the line on the bottom at 16:30? I feel like it's being cut off. How is myfunc being called in that?

Slides: speakerdeck.com/pycon2014/decorators-a-powerful-weapon-in-your-python-arsenal-by-colton-myers String itself: myfunc = skipIf(True, 'I hate doge')(myfunc)

thx

[@markwiygul6356]

How many decorators can I add. I'd like 3 or more in a column.

[@rednafi]

Infinite. But remember, with decorators you are calling the decorated function within a wrapper function. So It's not recommended to stack more than two as it can considerably slow down your function run time.
