title: skip an element in zip
body: <p>I have two files that are <code>zipped</code> with something like the following:</p>
  
  <pre><code>for line in zip(open(file1), open(file2)):
      # do-something
  </code></pre>
  
  <p>Unfortunately, now file2 has changed, and there is an additional line at the beginning. Yes, I could get rid of that manually (or with an additional script/program), but since the actual number of involved files is huge, I'd prefer to solve the problem at this level.</p>
  
  <p>So, what I want is something like the following (which would be valid, if open(file) were subscriptable):</p>
  
  <pre><code>for line in zip(open(file1), open(file2)[1:]):
      # do-something
  </code></pre>
