title: How to check if a list has an empty string
body: <p>Suppose I have a list <code>['', 'Tom', 'Jane', 'John', '0']</code>, and I wrote the following to check if it has empty string <code>''</code>:</p>
  
  <pre><code>if any('' in s for s in row[1:]):
          print "contains empty string, continue now"
          continue
  </code></pre>
  
  <p>I expect this to only pick the empty string, but this also picks a list that contains '0'. The '0' string is valid and I do not want to filter it out. So how can I check for an empty string in a python list?</p>
