Python 3.13.0 (final) has been released
Python 3.13.0 (final) has been released
After all the shenanigans two weeks ago – everyone discovering nasty little problems in release candidate 2 – the last week was suspiciously quiet, and therefore I can finally say: Python 3.13.0 is now available This is the stable release of Python 3.13.0 Python 3.13.0 is the newest major release...
Wow, they (apparently) finally made the REPL not suck! I always thought it was weird how shit it was given that it's one of the big reasons Python has become as popular as it is.
Maybe in another 20 years they can make the package tooling not suck too.
The Python REPL was always sort of minimal when used from the command line, but is quite usable in an Emacs window. IDLE is also useful some of the time. I never felt the need for anything like Eclipse because of it.
Maybe because people who needed it knew there were better ways to do it, like ipython and Jupyter. I’ve never heard of anyone gushing about the stock REPL.
Now only have to wait for:
- pyenv release
- pycharm update (including terminal)
- 3rd party libraries
to catch up…
Once that happens it'll be just couple of years until trickles down to corpo I work at :(
We got Python 3.10 in our Hadoop/Spark setup recently. I'm really enjoying those improved debug messages, man.
Protip:
pip install pyupgradeAnd thenfind . -name '*.py' -not -path '*.tox*' -print0 | xargs -0 pyupgrade --py310-plusin your repo to update what can be updated.BTW, pyupgrade's creator,
asottile(that's his name) also has an informative channel: Anthony Writes Code where he explains Python features, or goes into interesting bugs he ran into, etc. The good stuff.
Wait how does one make enough money to afford the JetBrains suite? I just do everything in VSCode.
Nice I guess it's time to check if my daily used libraries have stable 3.12 releases already.
I guess the free-threaded mode and the JIT compiler will be the most important features from what I read, but their significance is out of my expertise.
My absolute favorite with this update is the new REPL! It features Multiline-editing and a paste mode for easier pasting code. It also added the spaces automatically in my example.
Sometimes I want to make some quick tests on some data in the terminal without installing IPython to my environment first, this is great news!
This new error message will also be very useful for beginners and relieve StackOverflow:
AttributeError: module 'numpy' has no attribute 'array' (consider renaming '/home/me/numpy.py' if it has the same name as a third-party module you intended to import)That last one is going to be so good. Months ago I ran into that while porting the "Crafting Interpreters" java-based interpreter into python. It took me a few hours to figure out that one of my modules was colliding with "token" in the stdlib, a module I didn't even know existed. Glad it's being made clearer.
Woo!
We're still on 3.11, but it's been some time since I last checked compatibility with the later releases. Good job everyone, I'm going to be playing with this over the next couple weeks to see if we can upgrade to it.
So I remember the plan to improve Python's speed from 3.9 to 3.13... Has there been an updated plan since? I presume the JIT will likely be faster in 3.14 (it';s already at parity - pretty impressive for a first release), but is there anything else planned?
Docstrings now have their leading indentation stripped
I foolish thought that it meant that finally python introduced a hassle free simple way to have indented triple-quoted literal strings. But no. It baffles me that you cannot have simple literal strings that are indented. This is specially annoying if you are using them as templates to output multiline text.
