title: unicode way to write "hello world" in python
body: <p>I came across this code, and I wondered how it works. Could someone explain how this works. And if you could, could you explain how to write this in a different way without the numbers? Thanks!</p>
  <pre class="lang-py prettyprint-override"><code># coding: unicode_escape
  
  def hello():
    return \x27Hello, World!\x27
  </code></pre>
  <p>apparently, the comment is necessary. So if someone could explain it, and tell how to do it different without numbers, I would appreciate it.</p>
  <p>Thanks!</p>
