title: Unexpected type(s): (int, int) Possible type(s): (SupportsIndex, None) (slice, Iterable[None])
body: <p>What's wrong with this code:</p>
  <pre class="lang-py prettyprint-override"><code>split_list = [3600, 3600, 3600, 3600, 3600, 3600, 3600, 3600, 45]
  split_list2 = [None, None, None, None, None, None, None, None, None, None, None, None]
  result = [3600, 3600, 3600, 3600, 3600, 3600, 3600, 3600, 45, None, None, None]
  
  for i in range(len(split_list)):
      split_list2[i] = split_list[i]
  </code></pre>
  <p>In PyCharm it issues a warning;</p>
  <blockquote>
  <p><em><strong>Unexpected type(s): (int, int) Possible type(s): (SupportsIndex, None) (slice, Iterable[None])</strong></em></p>

  <p>But the script runs just fine and this code works exactly as I expected. I don't like warnings in my IDE though, any quick fixes?</p>
