I'm so glad they got rid of the stubborness. I remember they were discussing about this some time ago and said they don't want it. There's so many situations where a switch case represents the "way-to-go" over the ugly nested IFs.

Details for error messages seems cool, no more headaches with indentation errors when for some reasons your editor's linting and auto format extensions aren't working and you've refactored or c/p some if statements. No need to check line by line if it's 1 pixel to the left/right.

I had created a small 3D app with Python as an exercise recently (using pygame, pyopengl and pyopengl-accelerate). Today I installed Python 3.10, built pyopengl and pyopengl-accelerate from the dev branches for it, and ran the app again. With Python 3.9.6, it was around 30% faster (233 fps vs. 164 fps). I was quite surprised, since I had expected the opposite to happen.

Where is the "Update to latest version" in python? How do i do it and run all my old .py projects without worrying that some modules or some dependencies were not lost along the way? Thank you!

@Khelso 2 года назад

You would have to manage your environments for your old projects. For example, if you created a Tic-Tac-Toe game using Python 3.8.2, create an environment that uses that version of Python and don't update/change that specific environment. This is one of the advantages of Anaconda, if you use conda.

@tituss1421 2 года назад

@@Khelso Thank you for your answer! I'm not a professional software engineer and i don't code that much but I am a project manager in a software company and seeing the lads use c# and easily updating and not worrying about backward compatibility and all the jazz just makes me feel very sad for python. It's like this language was made to be taken seriously. Just for anyone to make a first step into coding and then move on to something more powerful and better maintained. I know i sound a bit frustrated but i really am. I don't use conda and i don't use jetbrains i just install python and i go with idle, i just like it that way. On linux, i open the console and write my .c programs in vim. I'm not yet at the level when i would find third party "help" useful. Cheers Seth!

@adarshdwivedi6630 2 года назад

@bagoquarks 2 года назад

*THE MATCH-CASE* may be a better branching solution if you are staring at an 'ELSEIF' or equivalent in any language's syntax, i.e. 3 or more forks in your IF block with perhaps the need for more to be discovered. I first used it in the '80s in SAS, an early data warehousing product from the SAS Institute. In later years and languages I would start a shell error trap code block and terminate it with the equivalent of a 'case _' block; unhandled runtime errors would emerge during testing and the code would be improved by adding new 'case' blocks to fix or report the error as appropriate. This is a very welcome improvement to Python. Thank you for the overview. I am new to Python and I'm hoping these features are promptly migrated to the Python forks being maintained for microcontrollers.

Finally... Switch is here... 🙌 Don't know why they changed it to match..🤔

@patloeber 2 года назад

because it's a little bit different than switch/case. it's a little bit more powerful since you can match whole patterns and not just single values.

@danielegvi 2 года назад

It's a feature in many other languages. It's more powerful and much more ergonomic than a switch, while still being able to do everything a switch does. As an example, switch has fall-through in many languages, and you must add a break statement for the most part. Match statements do away with that and instead use the "|" operator to create patterns. That's why they're called "pattern matchers", and that's where "match" comes from.

@@Thomas-vd7ez This is not Python specific, other languages use it too (Haskell, Scala, Rust). Pattern matching (match-case) is way more powerful than switch-cases, while can also be used in the same way switch-cases do.
