title: When to use triple single quotes instead of triple double quotes
body: <p>Learn Python the hard way, exercise 10.2:</p>
  
  <pre><code>tabby_cat = "\tI'm tabbed in."
  persian_cat = "I'm split\non a line."
  backslash_cat = "I'm \\ a \\ cat."
  
  fat_cat = """
  I'll do a list:
  \t* Cat food
  \t* Fishies
  \t* Catnip\n\t* Grass
  """
  
  print tabby_cat
  print persian_cat
  print backslash_cat
  print fat_cat
  </code></pre>
  
  <p>2: Use <code>'''</code> (triple-single-quote) instead. Can you see why you might use that instead of <code>"""</code>?</p>
  
  <p>I can't see why I might use <code>'''</code> instead of <code>"""</code>. It gives me the same output. Can someone explain me why I would use triple-single-quote instead of triple-double-quote? What's the difference between them?</p>
