title: Python RuntimeWarning: overflow encountered in long scalars
body: <p>I am new to programming. In my latest Python 2.7 project I encountered the following:</p>
  
  <blockquote>
    <p>RuntimeWarning: overflow encountered in long_scalars</p>
  </blockquote>
  
  <p>Could someone please elaborate what this means and what I could do to fix that?</p>
  
  <p>The code runs through, but I'm not sure if it is a good idea to just ignore the warning.</p>
  
  <p>It happens during an append process like:</p>
  
  <pre><code>SomeList.append(VeryLongFormula)
  </code></pre>
