title: Pandas df.describe() - how do I extract values into Dataframe?
body: <p>I am trying to do a naive Bayes and after loading some data into a dataframe in Pandas, the describe function captures the data I want.  I'd like to capture the mean and std from each column of the table but am unsure on how to do that.  I've tried things like:</p>
  
  <pre><code>df.describe([mean])
  df.describe(['mean'])
  df.describe().mean
  </code></pre>
  
  <p>None are working.  I was able to do something similar in R with summary but don't know how to do in Python.  Can someone lend some advice? </p>
