I created a new PEP proposal to try to remove a small footgun with assert statements 🔫 Is quite sneaky and Python already warns but I think is better to make Python do what people expect instead of just saying "your code is wrong, change it this way" 😉

@anthonypjshaw In Python 3.11 there will be almost no overhead for Python to Python calls thought. Mark and I worked on inlining the ceval loops so there is no consumption of the C stack. And the references to the arguments are stolen from the caller so there is close to 0 overhead 🚀

Yeah, no kidding! 😵‍💫 3.11.0a4 had a ridiculous amount of release blockers 🧐 we needed to solve and while everything was on fire we discovered something that made us make an early 3.10.2 release 🤯(you should upgrade: read the release notes for more info⚠️)! What a week 😅

#Python 3.10.2, 3.9.10, and 3.11.0a4 now available! 🚀 The first three releases of 2022 were cursed! What is usually a pretty mundane and largely automated process, turned out to be three separate curveballs. Fortunately, we didn't let 'em strike us out!

I assume the lesson here is "don't worry about what people think about your performance in interviews, in most cases it has almost no correlation with anything that matters" 😉

Feature freeze for 3.11 is upon us 🥶. The latest alpha release (3.11.0a7) is available for testing. Once the first beta for 3.11 is released in one month, no more features will be allowed in this version so if you have something in mind,now is the time🚀

Wanna see some ridiculously obscure bug of Python 3.11? 🐞🧙‍♂️ Check these two code samples. In the traceback of the first one, the last line is missing and the line number is wrong but changing the name of a variable (that doesn't even appear in the traceback) makes it work🤯

You haven't experienced true despair until you have gdb attached to another gdb attached to your program linked with a glibc version you just compiled yourself with extra debug symbols. I swear I am not making this up. The abyss is real and is made up of debuggers with bugs😵‍💫

As the person who released 3.10 and also added tons of new error messages in the parser, a new error message mechanism in the grammar and one entire new error message PEP, I would recommend to not ignore that smoke as it may be making too hard to appreciate the work of others

Third, horrible error messages. It's only in version THREE point TEN that they're even trying to make these readable. Heuristics help (ignore the smoke, look for the fire) but new programmers don't need pages of insane stack trace to get to a non-helpful error

This is super powerful because there are **a lot** of Python libraries that call native code 👾(C/C++/rust...) underneath and this will allow you to see how much time is spent on actual Python and how much in native code.🐍
