title: Left out 'print' function in Python, e.g. (print "hello world") vs ("hello world")
body: <pre><code>&gt;&gt;&gt; print &quot;hello world&quot;
  hello world
  &gt;&gt;&gt; &quot;hello world&quot;
  'hello world'
  &gt;&gt;&gt;
  </code></pre>
  <p>What is the difference?</p>
  <p>The Python <em><a href="https://en.wikipedia.org/wiki/%22Hello,_World!%22_program" rel="nofollow noreferrer">Hello, World!</a></em> example mostly uses:</p>
  <pre><code>print &quot;hello world&quot;
  </code></pre>
  <p>Can I strip that <code>print</code> and just use <code>&quot;Hello world&quot;</code> for giving a Python introduction?</p>
