title: Replace a specific range of values in a pandas dataframe
body: <p>I have big data set and there are tons of values which are way over average.
  For example,</p>
  
  <pre><code>    A         B
  1  'H'       10
  2  'E'    10000
  3  'L'       12
  4  'L'        8
  5  'O'       11
  </code></pre>
  
  <p>and I want to set <code>B2</code> cell as 0 and I tried this,</p>
  
  <pre><code>df['B'] = df['B'].replace([df['B'] &gt; 15], 0)
  </code></pre>
  
  <p>But didn't get any luck.
  How can make my data frame like this,</p>
  
  <pre><code>    A         B
  1  'H'       10
  2  'E'        0
  3  'L'       12
  4  'L'        8
  5  'O'       11
  </code></pre>
  
  <p>Thank you!</p>
