How to use yapf as formatter of Python

[MoienBowen]

I followed the documentation, it works with your suggested formater black as

  "language_overrides": {
    "Python": {
      "format_on_save": {
        "external": {
          "command": "black",
          "arguments": ["-"]
        }
      }
    }
  }

So I tried with yapf, it works without any argument as

  "language_overrides": {
    "Python": {
      "format_on_save": {
        "external": {
          "command": "yapf",
          "arguments": []
        }
      }
    }
  }

However, I would like to change the tab length as 2, hence, I need to add the option --style='{based_on_style: pep8, indent_width: 2}'. It does not work when I modify the settings.json as follows

  "language_overrides": {
    "Python": {
      "format_on_save": {
        "external": {
          "command": "yapf",
          "arguments": [
            "--style='{based_on_style: pep8, indent_width: 2}'"
          ]
        }
      }
    }
  }

Is there any one who could help me on this, please?
