Very useful. Thank you.

This is wonderful, thanks for documenting this!

Hello !

Do you know if there was a reason this following code was not proposed ?

deffind(seq,target):fori,valueinenumerate(seq):ifvalue==target:returnireturn-1

instead of

deffind(seq,target):fori,valueinenumerate(seq):ifvalue==target:breakelse:return-1returni

@frodon1 Raymond Hettinger actually mentioned that this example can be simplified using an early return. Seevideo. He said that for...else can be useful when a situation like this occurs "intermeshed with other more complex code in other operation so there is not a shortcut out".

I added notes for python 3 users. Could you please pull this changes?https://gist.github.com/mongoose11235813/151a04156e1a709ad6e4

@mongoose11235813 Thanks! You're changes have been merged. Sorry for the delay. Some searching turned up that github doesn't have notifications for comments on gists :(

For my (or other's) future reference on how I merged in the changes from your fork (since gists don't support pull requests):

 git remote add mongoose11235813 git@gist.github.com:151a04156e1a709ad6e4.git git fetch mongoose11235813  git merge mongoose11235813/master  git push origin master

There is yet a better way of counting things:https://treyhunner.com/2015/11/counting-things-in-python/

Hi, under "Using decorators to factor-out administrative logic" can you@JeffPaine please fix the if statement?

Cool!

Nice to see this written. Please changedicitonary keys todictionary keys.

It's so useful! Thanks

@robinchew: done, thanks! 😃

@DimitriPapadopoulos: Done, thanks! 🍰

All: glad everyone is enjoying and learning from this write up. Raymond Hettinger really gave a wonderful talk here!

Thanks for the notes@JeffPaine!

That was a great talk. The ratio content/time was huge. There's someone in the video comments (DarthChrisB) who time-stamped the video with each topic.

Thanks for sharing.

Interesting~

You should precise the library for defaultdict, influence, deque... Good job thank you !

Thanks for sharing.

this is awesome, thanks!

Typo on "Factor-out temporary contexts":

yieldfieldobj

Thanks so much for writing this up! I actually had just started to do the same, but then decided I should at least check online to see if anyone else already had!

I see@ikem-krueger mentioned this but you have a typo with theredirect_stdout function. It shouldyield fileobj instead of 'fieldobj'.

You can fork my fix below:

cool!

Thanks for sharing. This really useful!

Hi!

Hey. Small typo: explicidly -> explicitly.
Thank you very much.

I've addressed all comments here and moved this gist to a proper repo:https://github.com/JeffPaine/beautiful_idiomatic_python (so Pull Requests can be received and I get notifications, which isn't possible for gists).

If you have any other fixes / comments, please make them on that repo as I won't be checking back here again in the future. Thanks a lot!
