title: How can I get missing fields from json file in schema and vice versa
body: <p>I have installed <code>jsonschema</code> using <code>pip install jsonschema</code>.</p>
  
  <pre><code>from jsonschema import validate
  
  schema_data = {
      "type" : "object",
      "properties" : {
          "price" : {"type" : "number"},
          "name" : {"type" : "string"},
          "additional" : {"type" : "number"},
          },
      }
  
  json_data = {"name" : "Eggs", "price" : 34.99, "new": 90}
  </code></pre>
  
  <p>I am having above <code>schema_data</code> and <code>json_data</code> which is just validating the datatype.</p>
  
  <p>Here <code>additional</code> is an extra field in <code>schema_data</code> which is absent in <code>json_data</code>, and <code>new</code> is present in <code>json_data</code>  which is absent in <code>schema_data</code>.</p>
  
  <p>How can I list missing fields like <em><code>additional</code> is missing in <code>json_data</code></em> and <em><code>new</code> is missing in <code>schema_data</code></em>?</p>
