title: How to get the longest user name? (discord.py)
body: <p>I have a list of users ID, and I want to find the user with the longest name.
  But when I use <code>bot.get_user(id)</code> it returns None.
  I checked the ID, it is valid and does correspond to a user on the server.
  Code:</p>
  <pre><code>            for score in scores:
                  bad_chars = &quot;&lt;@!&gt;&quot;
                  for letter in score:
                      if letter in bad_letters:
                          score = score.replace(letter, &quot;&quot;)
  
                  print(score)
                  print(bot.get_user(int(score.strip(&quot;&lt;@! &gt;&quot;))))
                  member_len = bot.get_user(int(score.strip(&quot;&lt;@ &gt;&quot;)))
  
                  if member_len:
                      print(len(member_len.name))
                      if len(member_len.name) &gt; score_len:
                          score_len = len(member_len.name)
  
              print(score_len)
  </code></pre>
