title: How do I return a CSV from a Pylons app?
body: <p>I'm trying to return a CSV from an action in my webapp, and give the user a prompt to download the file or open it from a spreadsheet app. I can get the CSV to spit out onto the screen, but how do I change the type of the file so that the browser recognizes that this isn't supposed to be displayed as HTML? Can I use the csv module for this? </p>
  
  <pre><code>import csv
  
  def results_csv(self):
  
      data = ['895', '898', '897']
  
      return data
  </code></pre>
