title: Auto format flake8 linting errors in VSCode
body: <p>I'm using the <code>flake8</code> linter for Python and I have many code formats issues like <code>blank line contains whitespace flake8(W293)</code></p>
  <p>I'm trying to auto fix these linting issues. I have these settings:</p>
  <pre><code>    &quot;python.linting.enabled&quot;: true,
      &quot;python.linting.flake8Enabled&quot;: true,
      &quot;python.linting.lintOnSave&quot;: true,
      &quot;python.linting.flake8Args&quot;: [
          &quot;--ignore=E501&quot;,
      ],
      &quot;editor.formatOnSave&quot;: true
  </code></pre>
  <p>I'm using the default <code>autopep8</code> formater but it seems that it does nothing.
  Nothing happens when I save the file or run the command <code>Format Document</code>.</p>
  <p>Is there any way to auto fix these linting errors?</p>
