I would say proper variable scoping in general. It would be awesome to have let variables in python!

  Variables are scoped just fine from my point of view. What do you mean by proper?
  • maxs 6y ago
    I meant to say block scoped. Variables in python have function or global scope but no global scope. E.g. you can say for x in ...: and then use x outside of the loop.

      I have no idea why you would want to declare an x in the loop, and then use it outside the loop. There are better ways of doing things. The fact that you can do such a thing in JavaScript is exactly why JavaScript is such a mess of a language with its globally-declared and hoisted variables. That sort of practice has never made sense, and is not a language design that Python should follow.
