I feel like Python should be much faster already. With all the big companies using Python and it's huge popularity I would have expected that a lot of money, work and research would be put into making Python faster and better.
Python 3.14 is here. How fast is it?

Did anyone short Cracker Barrel stock? If not, I have a hard time seeing why bots would have any interest in investing the time/money. There also didn't seem to be any political clout being gained by the complaints. More real-world is that I know tons of friends/relatives in the South and I don't know of even ONE that liked the redesign.
Rage baiting has value to certain groups.

#343More than 300 comments here and still no convincing answer. Why the community wastes time on trying to make CPython faster when there is pypy which is already much faster? I understand pypy lacks libraries and feature parity with up to date CPython. But… can’t everyone refocus the efforts and just move to pypy to add all the missing bits and then just continue with pypy as the “official python”? Are there any serious technical reasons not to do it?

#344Every time I hear news about Python language itself, it sadden me that, in 2025, PyPy is still a separate distinct track from mainline Python. That said, I wonder if GIL-less Python will one day enable GIL-less C FFI? That would be a big win that Python needs.
Well, they added an experimental JIT so that is one step closer to PyPy? Though would assume the trajectory is build a new JIT vs. merge in PyPy, but hopefully people learned a lot from PyPy.
There is some information transfer happening. Antonio Cuni was at the latest Coython developer sprint and shared some insights from PyPy https://antocuni.eu/2025/09/24/tracing-jits-in-the-real-worl...

It isn't.

You have answered your own question.
Seriously, though. PyPy is 2-3 versions behind CPython (3.11 vs 3.14) and it's not even 100% compatible with 3.11. Libraries such as psycopg and lxml are not fully supported. It's a hard sell.

It's all grown up now. Runs on Django for the admin panel. Not that flask ever failed. Just became easier to manage the user base that way.
because of Django admin? any downsides/notable warnings for people considering Flask v Django? any migration guide that's helpful?
To limit the amount of languages we support I recently rewrote one of our backend services from Go (with SQLC) to Python. I hadn't worked with Python "web" for a while and started with Litestar and also their Advanced-Alchemy. Part of the reason was that their DTO's and dataclasses seemed like a good way to skip Pydantic. Anyway, once models became complext it wasn't easy to skip Pydantic and it also wasn't easy to deal with Advanced Alchemy. One afternoon I got so annoyed with it I rewrote everything with Django Ninja. It took me 4-5 hours that evening to recreate all the previous weeks stuff with Django because of how good the batteries included are.
I'm not sure I'd ever use any other web framework than Django going forward, and I'm not using half of it (including the admin). I think Litestar is great by the way, Django is just so easy to produce with.

You hope it doesn't ? > [Donald Knuth] firmly believes that having an unchanged system that will produce the same output now and in the future is more important than introducing new features This is such a breath of fresh air in a world where everything is considered obsolete after like 3 years. Our industry has a disease, an insatiable hunger for newness over completeness or correctness . There's no reason we can't…
Kinda related question, but is code really just a math? Is it possible to express things like user input, timings, inteerupts, error handling, etc. as math?
I would slightly sort of disagree that code is just math when you really boil it down, however, if you take a simple task, say, printing hello world to the output, you could actually break that down into a mathematical process. You can mathematically say at time T value of O will be the value of index N of input X, so over a period of time you eventually get "hello world" as the final output
Howeveeerrr.. its not quite math when you break down to the electronics level, unless you go really wild (wild meaning physics math). take a breakdown of python to assembly to binary that flips the transistors doing the thing. You can mathematically define that each transistor will be Y when that value of O is X(N); btw sorry i can't think of a better way to define such a thing from mobile here. And go further by defining voltages to be applied, when and where, all mathematically.
In reality its done in sections. At the electronic level math defines your frequency, voltage levels, timing, etc; at the assembly level, math defines what comparisons of values to be made or what address to shift a value to and how to determine your output; lastly your interpreter determines what assembly to use based on the operations you give it, and based on those assembly operations, ex an "if A == B then C" statement in code is actually a binary comparator that checks if the value at address A is the same as the value at address B.
You can get through a whole stack with math, but much of it has been abstracted away into easy building blocks that don't require solving a huge math equation in order to actually display something.
You can even find mathematical data among datasheets for electronic components. They say (for example) over period T you cant exceed V volts or W watts, or to trigger a high value you need voltage V for period T but it cannot exceed current I. You can define all of your components and operations as an equation, but i dont think its really done anymore as a practice, the complexity level of doing so (as someone not building a cpu or any ic) isnt useful unless youre working on a physics paper or quantum computing, etc etc

I recall reading somewhere about some investor who wanted to take control of cb who drove this, so less shorting and more opportunistic drive down the price to buy more shares at a lower price.
