prettier seems to not working in VScode (python)

I don't actually know how these thins work, apparently prettier explains how to make it the main formatter on their page:

{
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "[javascript]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  }
}

but i dont even know how to set this things. anyways, my question is, after i complete my writing, when i type ctrl + s (save) on my vscode, it used to make it, well, prettier. but now it doesnt change anything (and it is not pretty at all).

now, at the bottom right of the screen, i see this: what i see on my bottom right corner for prettier

and if i click that, ahem, empty set (?) image next to prettier, it becomes a double tick, but it exist my coding area and enter the output section: after i click on the thing

and if i click back to my coding area, it again becomes an, well, empty set (?) symbol.

all the help is appraciated.

ps: this is my first question, please go easy on my

sincerly

It's probably missing something in your settings. VSCode allows you to edit your settings through GUI or text (using JSON syntax). Go to your settings using the GUI and type: "Format", then make sure you have enabled the option "Editor: Format On Save".

Depending your formatter settings, when you save a file it should work as you expected.
