QUESTION
Apparently, Python 3.10 / 3.12 is going to deprecate / remove distutils.
Unfortunately, I have not been able to find a replacement for the one and only function I am using from it; distutils.util.get_platform(). What is the replacement for this?
Note that platform is NOT an answer. I need a function that returns the complete string that is used when building a binary wheel¹, e.g. macosx-12-x86_64. Note particularly that there appears to be platform-specific logic embedded in this (e.g. the only other way I know to get the macos version is with a macos-specific API).
(¹ As noted in a comment, distutils.util.get_platform() is, strictly speaking, not that function. However, PEP 425 specifies that "the platform tag is simply distutils.util.get_platform() with all hyphens - and periods . replaced with underscore _." Ergo, it is straight-forward and platform-agnostic to derive the tag from distutils.util.get_platform(). An acceptable answer may therefore give an approved, public API which produces the platform tag directly, or a compatible replacement for distutils.util.get_platform().)

QUESTION
When I want to access a pickle data file in a sibling folder, I cannot use the same (relative) paths. Because I work with multiple collaborators, this results in having to change the file_path variable (see snippets below) after each git push/pull, which is annoying, and probably unnecessary.
File structure looks like this:

QUESTION
The example in this question seems to work only for fixed-length arrays, however the similar code below from https://frama-c.com/html/acsl.html doesn't seem to pass. As soon as I change the code to be include the requirement && n == 42 (or any other positive integer) it passes.
When it fails it says [wp] [Alt-Ergo 2.4.1] Goal typed_set_to_0_loop_invariant_established : Timeout (Qed:1ms) (1') (cached)
ANSWER
Answered 2022-Feb-15 at 08:48Actually, the loop invariant 0 <= i <= n is not true if n is strictly negative. A loop invariant must hold the first time you reach the loop (this is what the "established" part means, as opposed to the "preserved" part in which you must check that it holds at the end of any loop step, assuming it was true at the beginning of said step), even if you don't end up entering the loop at all (which is obviously the case here if n<0). You must thus add a requires n >=0; in the contract of the function.
EDIT
I forgot to mention that another solution is of course to make n and i unsigned (or even better to #include and use size_t): this way, you are guaranteed a positive number without having to write an additional requires)

Answered 2021-Dec-27 at 18:01The solution is to add $('#featured-image').html(data); to the script, which pass the data output to html.
QUESTION
I'm trying to make website which shows posts featured image on link hover.
Example:
So I started to learn basic jQuery and php and I tried to achieve that by using get_the_post_thumbnail($post_id); function which return image basing on post id. To get id I used url_to_postid(); Wordpress function. As it states it: "Examine a URL and try to determine the post ID it represents." so the $url is required. So i thought I can deliver the variable by writing script, which gets 'href' from on mouseover:
