title: Why does `False is False is False` evaluate to `True`?
body: <p>Why in Python it is evaluated this way:</p>
  
  <pre><code>&gt;&gt;&gt; False is False is False
  True
  </code></pre>
  
  <p>but when tried with parenthesis is behaving as expected: </p>
  
  <pre><code>&gt;&gt;&gt; (False is False) is False
  False
  </code></pre>
