I'm so glad Python is getting more performant and receives even more QoL features lately. I'm not a Python dev, but I've been keeping an eye on it due to it being the standard for ML/AI nowadays. Thanks for yet another informative video, keep them coming! #py311 P.S. Waiting for the Gentoo announcement for migrating to 3.11 woot!

If only every language's compiler/interpreter would do the same. About 20-ish years ago, the Digital Mars C++ compiler could do this exact thing with error messages in C++. It's not still getting updates, so it can't handle a lot of the newer standard stuff, but if it could be done with C++ post-templates, then every compiler/interpreter should do it.

Interested to see how the speedup improves my terribly inefficient scripts. Also endless praise to Mr. Salgado for making errors more bearable; the improved exception handling also makes me excited to write buggier code just to admire the vastly improved debugging process. I've been toying with rust and as everyone said, the compiler errors are a thing of beauty compared to other languages I've tinkered with, hopefully we start to see some of the same love for Python's interpreter. #py311

I respect what you said about SQL queries however I'm a data analyst and often have to deal with huge tables (50+) columns and with format strings you -can read/understand a lot more clearly what's going on (imagine 50+ columns and adding another one) -dont need to specify the parameters in order which is HUGE considering most of the stuff I'm working with comes in whatever form but lists in correct order -can easily generalize requests with string addition and functions (especially search queries where you dont need all SQL filters) -can easily convert from other data types I dont do stuff on the web, so that might be a niche opinion, but in my opinion string-ized requests are justified. (If there is a better option that does not require me to format my data into a sorted list let me know)

The better error messages is the only thing that really interest me here in #py311 . I'm a noob learning and being told exactly and explicitly where i messed up is simply amazing. Making python faster also seems neat. When you're starting to learn programing, wondering if learning python is really the best language because some are faster kind of is a big deal. "Should i really try to use pygame to make simple game or directly switch to c++ and unity once i get things going after learning some python" is a legitimate question newbs ask themselves.
