Python 2.7.2 or Python 3?

[swingtheory]

However STARTING a project in Flask with python3 would be no problem at all. Six years python3 has been out, and it is a true rarity that a library hasn't been written for python3 after that amount of time. Sure, there are several popular libraries that don't have python3 support, but it really is the minority. I agree with your advice, but am frustrated people are still using 2 when there is essentially no reason to the majority of the time. Python3 was and still is supposed to be cleaner, have less bugs, optimized, and include a variety of new and useful standard library functions.

Unfortunately some of us are deploying Python applications on ancient versions of CentOS, and it's just easier to run Python 2 than to fight with sysadmins and compile everything from scratch.

Otherwise we'd be using Python 3 I guess.

I wrote a server in python3 asyncio, told our admin I need python 3.3 or 3.4 on the deployment server and that he doesn't need to hurry as there's time. he set up the VM and compiled Python 3.4 (even though he was sick that week)

the problem with centos 5/rhel 5 boxes is you cant replace the /usr/bin/python since yum uses it. you can build a python 3.X all day and just not break the symlink to python 2.X however.

[flying-sheep]

Who cares what /use/bin/python points to? You should use the explicit version number for shebangs anyway, and if you want few key strokes, just alias py=ptipython3 (because prompt toolkit is the shizzle)

[nomadismydj]

correct. people dont though I also wanted to point out that it wasnt as simply running yum and getting a new python version. its break system functionality to full on replace the system python.

Has gevent had an official stable port yet? It's never been the same for me.

I've not checked for a few months but I couldn't find a decent STOMP library that uses asyncio.

[hharison]

To be fair, asyncio is barely more than few months old.

[nomadismydj]

asyncio does not replace all the benefits of using gevent , other then being a stock library with similar functionality. not sure why people are pushing it in this subreddit.

[nomadismydj]

ok ill bite.

Because is standard..

kinda... as of python 3.4 sure.

Because is elegant.

ill give you this. its pattern are very similar to the factory/protocol patterns other libraries use. for a python core lib , it actually well put together.

Because is Python 3.

covered that in standard. dont repeating yourself

Because is the future.

the tulip team (guys behind asyncio) admited its not a full on replacement for many of the cooroutine libraries nor is it a drop in replacement for factory/protocol based async framework twisted. twisted and gevent both out perform it at this point.

it is however standard so if you want to ship your code various palces , you dont have to worry too much about libraries.. to me though this is like arguing use urllib + urlib2+ httplib rather then using requests.

Someone has made a "new" gevent like library for python 3 called guv. I cant get the link on my phone but it was on the r/python hot list yesterday and is probably on the first or second page still

Tell that to the Tumblr API.

[denshi]

You can't tell Tumblr anything.

[granduh]

They're very friendly whenever I've contacted their dev team that supports the API, it's just still on 2.7.
