title: Python 3.5 not opening a zip file
body: <p>I'm not able to open the file downloaded from <a href="https://data.cityofnewyork.us/dataset/Broadband-Data-Dig-Datasets/ft4n-yqee" rel="nofollow noreferrer">this URL</a> using Python's <code>zipfile</code> facility.</p>
  
  <p>This file <em>does</em> open using my Mac's built-in deflater, however, and <code>python-magic</code> (via <code>import magic; magic.from_file("...")</code>) reports that the file is:</p>
  
  <p><code>'Zip archive data, at least v2.0 to extract'</code>.</p>
  
  <p>Yet when I do:</p>
  
  <pre><code>with open("498200/Broadband Data Dig - Datasets/NYC Connected Broadband Data Dig Files.zip") as fp:
      zipcontent = zipfile.ZipFile(fp)
  </code></pre>
  
  <p>I get:</p>
  
  <p><code>BadZipFile: File is not a zip file</code></p>
  
  <p>My Python version is <code>3.5.2</code>. What's going on here?</p>
