title: How to calculate a densitiy distribution for a set of values in python?
body: <p>I have a pandas data frame and would like to calculate density distribution function for these values. Would be nice to have something like that:</p>
  
  <pre><code>df['col_name'].dens()
  </code></pre>
  
  <p>However, if something like that does not exist, I can put all these value to a list and then use some other functions that calculate a density distribution function for values in a list. It would be great if I can do it in either of these packages: <code>scipy</code>, <code>numpy</code>, <code>ipython</code>, <code>scikit</code>.</p>
