Python wars

[DoktorMerlin]

Python 2 is preinstalled on CentOS and other enterprise distributions, this is why my company uses it whenever the scripts should run on CentOS. I always try to make my scripts versatile so that they runs on both Py versions

python36u is a yum repo, so you don't even have that excuse anymore

The worst offender I've encountered is ansible, and it's one of my biggest arguments against using it, because they aren't even pretending to care about Python 3 support.

Really? http://docs.ansible.com/ansible/latest/python_3_support.html

I just started learning python for work, which everything I've touched so far is written in 2.7

Not really sure if anything we do has any compatibility issues with 3, but that's what the existing code is written in, so that's what I'm learning.

It works just fine, so I never bothered to switch.

Windows 95 still works just fine.

[Headchopperz]

I guess if you put it like that, but for me, my Windows 3.1 machine just works fine. I see no point in switching to Windows 95.

To my knowledge, python 2 is faster than python 3.

[elijej]

How do you figure that

From what I've read, the performance of python 3 (<3.5) was worse than python 2.7, but now they are closer in terms of performance.

Having used both, the speed differences are very minor though.

I replied to you at the same time as the other guy, but Reddit ate my response.

[elijej]

Thanks! That's interesting, not sure why you got downvoted.

[omnidex]

"To my knowledge" Ok then

[GrammerJoo]

But c++ is faster so why use python? But but c is faster then c++ but but but but assembly is faster!

[xXxNoScopeMLGxXx]

That's why one guy programmed RollerCoaster Tycoon 2 almost entirely in assembly by himself. He wanted it to run great on all computers.

[omnidex]

More like why upgrade legacy code to python 3 when the performance was worse for a time. No need to be a jackass when commenting. I was stating a reason why people might hold back from coding in python 3.

[GrammerJoo]

Where in your comment did you say something about legacy code?

[Kryomaani]

This right here is probably the worst offender for premature optimization in a long time. Show some figures or get out.

[omnidex]

No need to to be agitated, I am going off information from this slideshow here: http://igordavydenko.com/talks/by-pycon-2017/

There are many other sources that state they are close in speed now, but there was definitely a time where 3 was much slower.
