title: Python pandas: oposite of pandas.Series.str.match
body: <p>How to Determine if each string in a column does not start with a match of a regular expression.</p>
  <p>I need to check when a Column does NOT equal a string.</p>
  <p>I've found:</p>
  <pre><code>pandas.Series.str.match
  </code></pre>
  <p>And it is almost what I need, but I want to get True when the string is NOT a match</p>
