@DonJayamanne here

@zjjott "here" what?

[brettcannon]

So are you saying you can reformat files for about 10 seconds (which is really specific and fast to notice a reformat), but then it simply stops working? And can you tell us what settings you have turned on for auto-formatting on save?

[zjjott]

@brettcannon no,I mean vscode can autoformat python file,only when I just open vscode or just modify any settings.
autopep8 doesn't behavior after a while and when I save python file, console have error like this:

15  console.ts:123 [Extension Host] (node:33010) DeprecationWarning: Calling an asynchronous function without callback is deprecated.

process.nextTick @ internal/child_process.js:766

all my setting is that:

{
  "editor.fontSize": 18,
  "terminal.integrated.fontSize": 20,
  // "editor.wordWrap": "bounded",
  "editor.fontFamily": "Monaca, Menlo, Monaco, 'Courier New'",

  "python.envFile": "",
  "editor.wordWrap": "on",

  },

  "go.useCodeSnippetsOnFunctionSuggest": true,
  "go.goroot": "/usr/local/go",

    ".env/**": false,
    ".env3/**": false
  },
  "[python]": {
    "editor.formatOnSave": true
  },
  "explorer.confirmDelete": false,
}

BTW,as you can see, I have setting formatOnPaste, and it works well, but formatOnSave not
