title: What is a=b=c in python?
body: <p>I am quite confused, consecutive equal <code>=</code> can be used in python like:</p>
  
  <pre><code>a = b = c
  </code></pre>
  
  <p>What is this language feature called? Is there something I can read about that?</p>
  
  <p>Can it be generated into 4 equals?</p>
  
  <pre><code>a = b = c = d
  </code></pre>
