title: Remove rows in python less than a certain value
body: <p>I feel like this question must have been answered by someone before, but I can't find an answer on stack overflow!</p>
  
  <p>I have a dataframe <code>result</code> that looks like this and I want to remove all the values <em>less than or equal to</em> 10</p>
  
  <pre><code>&gt;&gt;&gt; result
                         Name              Value      Date
  189                   Sall                19.0  11/14/15
  191                     Sam               10.0  11/14/15
  192                 Richard               21.0  11/14/15
  193                  Ingrid                4.0  11/14/15 
  </code></pre>
  
  <p>This command works and removes all the values that are 10:</p>
  
  <pre><code>df2 = result[result['Value'] != 10]
  </code></pre>
  
  <p>But when I try to add the &lt;= qualifier I get the error message <code>SyntaxError: invalid syntax</code></p>
  
  <pre><code>df3 = result[result['Value'] ! &lt;= 10]  
  </code></pre>
  
  <p>I feel like there is probably a really simple solution. Thanks in advance!</p>
