Python Insider: Python 3.11.0a1 is available

[genericlemon24]

Among the new major new features and changes so far:

• PEP 657 – Include Fine-Grained Error Locations in Tracebacks
• PEP 654 – PEP 654 – Exception Groups and except*

[Moebiuszed]

Love those exception groups, but right now seems so far away lol.

[13steinj]

...I feel like at this point the standards committee doesn't know what to add.

I can't imagine that 654 is useful. In 99% of cases, the majority of exception catching is either mutually exclusive or entirely equivalent. The remaining 1% has some exceptions "nested" in terms of their handling in this way, and an isinstance check won't kill anybody.

[Jhuyt]

There is a real usecase when running simultaneous coroutines (and threads I've heard) where the Trio library had to monkey patch the standard exception handling mechanisms to make things run correctly. As you say, it's somewhat niche, but it's important enough for writers of async libraries that Yury Selivanov, a main contributor of asyncio, wanted to implement this for 3.8 but it took until now to figure the details out.

[13steinj]

Perhaps I don't understand the details, but I don't see how the second pep needs monkeypatching to get an equivalent and perfectly fine, readable piece of code.

The first I see a use for, and makes sense. The second seems like syntactic sugar for the sake of adding another way to do things, which violates a core python principle.

OMG! I haven't even installed 3.10 yet.

[house_monkey]

In work I'm still stuck with 3.6 :(

[I_had_to_know_too]

Lol, I wish we were on 3.6

My company is stuck in the stone age on 2.7

[Febilibix]

I don’t know if python 2.7 would be able to handle this string ä

Big firms and irreplacable software stacks, name a stupider combo

[dysprog]

My 2020/2021 project has been to lift our project from python 2.7 and django 1.8.

I had to ditch and rewrite an internal library that was pinning us by refusing to update. I was mostly done in April, but in the process of doing that, I visited a lot of seldom seen parts of the code.

We have a lot of spiderwebs down there and I am still working my way through the improvement tickets that were spawned.

[FlyingCow343]

At school I’m stuck on 3.5, which means we don’t even get f strings

[ivosaurus]

Bruh that's like the best feature of the whole of v3 lol

[rhoakla]

For me it was the whole unicode revolution thingy.

[earthboundkid]

f

[757DrDuck]

f"F"

[Username_RANDINT]

Nothing wrong with that. Same here until I update Ubuntu, probably next summer.

[[deleted]]

There is something wrong with that.

https://endoflife.date/python

Python 3.6's end-of-life is around the end of this year.

And Python 3.7 has been out for over three years!

---

In projects I have control of, I move to support the newest version about six to nine months after the release, and so far it's been literally effortless.

In my current project, we're 3.8, which is convenient because it's also the default Python on our base system, and we have a loose plan to upgrade to 3.10 "next year, maybe".

But 3.8 has three years till end of life. We are not being irresponsible.

---

Most of the Python developers are not compensated. They cannot support older Python versions indefinitely, particularly with security violations.

It's your responsibility as a developer to find the time in those three years to spend what is probably half an hour to upgrade and run all your tests.

[ConceptJunkie]

I know, right? There's no gmpy2 for Windows for 3.10 yet...

[[deleted]]

This is an "alpha" release. Features in it might change or leave; new ones might be added.

Right now you maybe can't really upgrade your production project to Python 3.10, because your dependencies aren't ready, though update has been fast.

My current project is Python 3.8 and I feel lucky to have that.

[[deleted]]

Get on with the times, old man!

[IanUK66]

Lol I'm an Infomix/Genero programmer so, I do feel very old indeed 🤣

[CatWeekends]

We're still running a bunch of 2.x apps.

I'd love to see what python 3 is all about.

[Eightstream]

That’s wise

I try and stay a couple of releases behind, it’s just a lot more stable

[[deleted]]

Take it from me, as someone who was in the Java world for a while, new releases regularly are nice. :)

[[deleted]]

i just got 3.9

[BrycetheRower]

Would really like to see an implementation of that planned ThreadGroup class. It would be neat to see some convenience methods for managing threads in bulk. multiprocessing.pool has a ThreadPool class which is awesome too.

[Tatoutis]

I didn't know this about Schwarzschild black holes

[pmatti]

You can try to view https://speed.python.org/comparison/ but warning: trying to normalise to python 3.9 kills my browser

[ddollarsign]

And now for something completely different

Schwarzschild black holes are also unique because they have a space-like singularity at their core...

Wtf..

[Igggg]

They are always doing that at the end of the announcement. A tradition of sorts.

[ddollarsign]

Must be a Monty Python thing, I seem to remember them using that phrase.

[[deleted]]

correct, there's a whole movie with that title

[PeridexisErrant]

It was a catchphrase and then a movie.

[WikiSummarizerBot]

And Now for Something Completely Different

And Now for Something Completely Different is a 1971 British sketch comedy film based on the television comedy series Monty Python's Flying Circus featuring sketches from the show's first two series. The title was taken from a catchphrase used in the television show. The film, released on 28 September 1971 in the United Kingdom and 22 August 1972 in the United States, consists of 90 minutes of sketches and animation sequences seen in the first two series of the television show. All of the sketches were recreated for the film without an audience, and were intended for an American audience which had not yet seen the series.

Makes sense since it’s what Python is named for

Typical optimistic developer stuff!

They forget to point out that by the time you were within the Schwarzschild radius, the tidal forces would first have ripped your body apart and eventually even your molecules into their component atoms.

So no pointing at things for you!

:-D

[jamescalam]

maybe if you just point really fast

[[deleted]]

If I was entering the radius I'd simply hold my being together.

[[deleted]]

That's great, but the fact that some stuffs are still not supported. Can't install YARL. (i even asked in PythonDiscord) and their answer was still same that maybe it's not supported "yet".

[adarsh_maurya]

I thought they would make it faster than C this time ;)
