title: Don't convert newline when reading a file
body: <p>I'm reading a text file:</p>
  
  <pre><code>f = open('data.txt')
  data = f.read()
  </code></pre>
  
  <p>However newline in <code>data</code> variable is normalized to LF ('\n') while the file contains CRLF ('\r\n').</p>
  
  <p>How can I instruct Python to read the file as is?</p>
