title: editing roles with edit_role discord.py
body: <p>I have the following line in my script:</p>
  
  <pre><code>await client.edit_role(server='547874634978789398', role='' ,colour=0x008000)    
  </code></pre>
  
  <p>However I do not understand what parameter discord.py is expecting for <code>role=</code>. Can anyone point me in the right direction to better understand this parameter?   </p>
