title: How to find range overlap in python?
body: <p>What is the best way in Python to determine what values in two ranges overlap?</p>
  
  <p>For example:</p>
  
  <pre><code>x = range(1,10)
  y = range(8,20)
  
  (The answer I am looking for would be the integers 8 and 9.)
  </code></pre>
  
  <p>Given a range, x, what is the best way to iterate through another range, y and output all values that are shared by both ranges? Thanks in advance for the help.</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>As a follow-up, I realized that I also need to know if x does or does not overlap y. I am looking for a way to iterate through a list of ranges and and do a number of additional things with range that overlap. Is there a simple True/False statement to accomplish this?</p>
