Python survey 2020

[compsystems]

Hello
What does Python need to be a super language?
If you want you can share your ideas in this forum and in the following survey.

https://surveys.jetbrains.com/s3/c8-pyth...urvey-2020

1: A type of symbolic object for algebraic manipulation CAS
2: ...


There is also a draw with 100 winners (surprise prize) to whoever completes the form

Is it well translated in multiple languages, or did you have to answer in French?
It is a high quality survey.

I know they won't add it, but Python could use a DO-WHILE or REPEAT-UNTIL or equivalent loop structure where the condition is evaluated at the end of the loop. I don't know that I've ever used a language without such a loop construct. I know you can use a "while True:" and a "break" but that looks so kludgy.

(On the plus side, I don't know that I've seen another language with the while-else construction that Python has. That's kind of cool.)

Assumed Python do have repeat/until:

repeat:
      ... # some code
      if condition: continue
      bad = 0
      ... # code that might turned "bad"
until bad

if condition is true, it will jump to line "until bad".
However, bad is a local variable, not existed before condition test.
(Or worse, bad existed outside repeat/until loop, and used for until ...)

You could solve it by moving up bad=0 before the condition test.
But, that would be messy to document repeat/until usage.

Static typed language does not have this problem. Code won't compile.

A native BCD decimal data type would be a big step in the right direction. C# handles it very well.

You can do this:

Code:

while True:
   do something
   do some more
   a += 1
   If a >= 10:
      Break

That's the equivalent of

Code:

DO
   do something
   do some more
   a = a + 1
LOOP WHILE a < 10

I know you think it looks kludgy as did I, coming from a BASIC background, but if you use Python for a while you get used to it. Since Python programmers think in terms of While True, there's no incentive to change it.
