title: Website to check Illegal variable names or keywords Python
body: <p>I may have stumbled on an illegal variable name</p>
  
  <pre><code>pass = "Pass the monkey!"
  print pass
  </code></pre>
  
  <p>Syntax error: invalid syntax</p>
  
  <p>I'm aware that some keywords are verboten as variables.
  Is there the Pythonic equivalent to <a href="https://mothereff.in/js-variables" rel="nofollow">JavaScript variable name validator</a>?</p>
