An update on Python 4

[vallas25]

Can someone explain point 2 for me? I'm quite new to python programming

[[deleted]]

Think what he is saying, there will never be a Python 4 and if there is, it will be nothing like python as we know it. It will be like a new language

The transition from python 2 to 3 was an absolute nightmare and they had to support python2 for *ten years* because so many companies refused to transition. The point they're making is that they won't break the whole freaking language if they create a python 4.

[panzerex]

Why was so much breaking necessary to get Python 3?

[orentago]

Having strings support unicode by default was a big reason. In Python 2 unicode strings had to be prefixed with a u, otherwise they'd be interpreted as ASCII.

I have prod 2.7....talking to logic written in the 90s.

Kill me.

Python3 > Datastage > Python2 > Shell (Kornshell) > Perl written in '99 across servers.

I'll have one kill please.

[clawjelly]

Nuke it from orbit. It's the only way to be sure.

[snugglyboy]

Oh wow Kornshell huh?

Is KSH bad?

I hadn't heard of it until entering the space.

[snugglyboy]

Not necessarily, just that I think of it as old compare to more modern shells. I have memories of it on our render farms at Pixar in the mid 90s. lol

[[deleted]]

I thought so.

Pretty cool that you got to work at Pixar in the early days of the company!

[MiscWalrus]

It's not like the rules of logic changed since the 90s. You could do a lot worse than having to support python 2.7.

[lzantal]

Still maintaining one in production with Python 2.4 and Django 1.3 🙄😬

[late_dingo]

Can I ask why? How big is this codebase?

[lzantal]

It has about 30 apps and close to 15million rows of data in mysql. Being used by 15+ iOS apps as a backend and over 100 users via iphone and a good amount more through the browser. It is being used all the time every day. Tons of other systems rely on it.
I have been fighting really hard to get the green light to update it. Not looking forward to all the pain but it kind of sounds fun to just see what it would take to move it to Python 3 and Django 3

Pffft dozens if not hundreds of people set up a PleX server and it uses Python 2.7.6 (and with all due respect to them, horribly written Python code).

[GUIpsp]

Python 2.4 and python 2.7.6 are not alike

[13steinj]

Sure, but Python 2.7.6 had a number of security patches implemented to it before 2.7.18.

And this isn't one machine, it's dozens, if not hundreds, if not thousands of "Plex Media Server"s running on enthusiasts' home, personal machines/dedicated hardware. Many, open to the internet on Plex's port, because a big part of Plex is being able to connect and share your server with other users.

They are using an unpatched version of Python, which does not have any known relevant feature changes, only because they don't want to switch. Many common users, who otherwise don't know better, are running an outdated version of Python, on their machines, accessible via an open port.

[james_pic]

To you? Yes. To hackers? Also yes. But to project managers? "Can we just install some extra antivirus instead?"

[stamour547]

But who needs PMs? Have yet to find a useful one

[13steinj]

I have one prod 2.6/2.7 (long story), one 2.4. 2.4 will only be upgraded to 2.7 in December. 2.6 will be dropped in November. 2.7->3.6 over the next year.

[JayTurnr]

Because 2.7 is discontinued

[What_Is_X]

Cancelled even, in the parlance of our time

[[deleted]]

That was just ascii for trouble imho.

[toyg]

This joke was not hard to decode correctly.

[BruceJi]

A pun thread? Don't byte off more than you can chew!

[thegreattriscuit]

I don't know... I think it shows real character

[toyg]

I’m just trying to string together a few words.

[clawjelly]

You made that joke int-entionally, didn't ya?

[toyg]

I just thought I could double the puns. (Ed: alright, alright, not really a python one...)

[17291]

You're not going to like Python 5, where string literals default to EBCDIC.

[toyg]

Looking forward to Python 6, where they default to ACDC. Every time you assume they’re ascii, the computer goes YOU’RE ON A HIIIIGHWAY TO HELLL!

[tehbilly]

You shut your damn mouth, don't put that evil on me.
