title: Can you iterate a number backwards without using a list?
body: <p>How would you iterate a number backwards without using a list in Python 3?</p>
  
  <p>Using lists, I would probably do something like:</p>
  
  <pre><code>li = list(range(100))
  for i in li[::-1]:
      print(i)
  </code></pre>
  
  <p>This is a fine solution, but it does not work with huge numbers.
  Right now, I'm trying to iterate a number backwards with large numbers, but an overflow error happens, so I think I need to somehow find a way to iterate a number backwards without using lists.</p>
  
  <p>Is there any way?</p>
