title: if pass and if continue in python
body: <p>I saw someone posted the following answer to tell the difference between <code>if x: pass</code> and <code>if x: continue</code>.</p>
  
  <pre><code>&gt;&gt;&gt; a = [0, 1, 2]
  &gt;&gt;&gt; for element in a:
  ...     if not element:
  ...         pass
  ...     print(element)
  ... 
  0
  1
  2
  &gt;&gt;&gt; for element in a:
  ...     if not element:
  ...         continue
  ...     print(element)
  ... 
  1
  2
  </code></pre>
  
  <p>What is the result for <code>if not element</code> when <code>a = 0</code>? Why when using <code>continue</code>, 0 is not printed?</p>
