title: How to custom indent json dump?
body: <p>I use indent = 2, but I want the first level of indentation to be zero. For example:</p>
  <p><strong>Partial Code</strong></p>
  <pre><code>json.dump(json_data, json_file, indent=2)
  </code></pre>
  <p><strong>Output</strong></p>
  <pre><code>{
    &quot;a&quot;: 1,
    &quot;b&quot;: &quot;2&quot;,
    &quot;list&quot;: [
      {
        &quot;c&quot;: 3,
        &quot;d&quot;: 4,
      }
    ]
  }
  </code></pre>
  <p><strong>What I want instead</strong></p>
  <pre><code>{
  &quot;a&quot;: 1,
  &quot;b&quot;: &quot;2&quot;,
  &quot;list&quot;: [
    {
      &quot;c&quot;: 3,
      &quot;d&quot;: 4,
    }
  ]
  }
  </code></pre>
