title: Python: Finding a "=" in a string
body: <p>Using the python find function, I want to determine whether a string has an "=" sign in it.
  It could find anything else other a "=".  </p>
  
  <p><code>string: Math="Fun".</code></p>
  
  <p><code>if (string.find("=") &gt; -1):</code></p>
  
  <p>Any ideas?</p>
