title: How to use Youtube API v3 to filter out videos by category?
body: <p>I'm trying to build a Youtube query in python that filters out, for instance, category 39 - Horror.
  I'm looking to something similar to this:</p>
  
  <pre><code>searchResults = YouTube.Search.list('id,snippet', {
      maxResults: "10",
      q: "The ring",
      type: "video",
      videoCategoryId: "-10"
    });
  </code></pre>
  
  <p>Or any kind of workaround.</p>
  
  <p>I even contemplated searching without filter and then try to exclude the ones from that category, but the information provided by the query does not include the category of the video. And it's pretty ugly as I really want 10 results, and I may need to make more queries in order to fill the list.</p>
  
  <p>All I've found googling is how to get videos from the specified category.</p>
  
  <p>Can you help me on how to achieve this?</p>
