title: I keep receiving AttributeError: 'set' object has no attribute 'items' when I run a get request?
body: <p>I keep recieving the error: "AttributeError: 'set' object has no attribute 'items'" when I try to do a get request using the request library.</p>
  
  <p>below shows what I have already tried.</p>
  
  <pre class="lang-py prettyprint-override"><code>gethooks = "https://api.github.com/repos/ORGANIZATION/REPO/hooks"
  response = requests.get(gethooks, headers={"Authorization: token GITHUBTOKEN"})
  print(response)
  </code></pre>
  
  <p>I expect to receive a JSON with information on that repos webhooks, but instead recieve that error.</p>
