title: Change point detection in python
body: <p>I have a pandas DataFrame where one column contains the following elements:</p>
  
  <pre><code>[2,2.5,3,2,2.6,10,10.3,10,10.1,10.3,10], 
  </code></pre>
  
  <p>is there a python function that can detect the sudden change from 2.6 to 10 from that list? I have read a little bit and <a href="https://cran.r-project.org/web/packages/changepoint/changepoint.pdf" rel="noreferrer">R</a> can do that. Is there a similar function in python?</p>
