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.
