title: How to compress a file with bzip2 in Python?
body: <p>Here is what I have:</p>
  
  <pre><code>import bz2
  
  compressionLevel = 9
  source_file = '/foo/bar.txt' #this file can be in a different format, like .csv or others...
  destination_file = '/foo/bar.bz2'
  
  tarbz2contents = bz2.compress(source_file, compressionLevel)
  fh = open(destination_file, "wb")
  fh.write(tarbz2contents)
  fh.close()
  </code></pre>
  
  <p><strong>I know first param of bz2.compress is a data, but it's the simple way that I found to clarify what I need.</strong> </p>
  
  <p>And I know about BZ2File but, I cannot find any good example to use BZ2File.</p>
