title: Issue reading csv file
body: <p>I am having trouble reading a saved csv with python:</p>
  
  <pre><code>import csv
  
  
  with open('blah.csv','rb') as csvfile:
      data = csv.reader( csvfile )
      row_count = sum(1 for row in data)
      print row_count
  
  
      r = 1
      for row in data:
          print r
  </code></pre>
  
  <p>My issue is that although python seems to recognise the file and recognise that row_count = 9 (and prints this) it doesn't print r for each row in the later loop.</p>
  
  <p>This code runs correctly on my computer, but not in the cloud on www.pythonanywhere.com</p>
