title: python for loop to print multiple lines of a descending range
body: <p>To get an output like </p>
  
  <pre><code>0 1 2 3 4 5 6 7 8 9 
    0 1 2 3 4 5 6 7 8 
      0 1 2 3 4 5 6 7
        0 1 2 3 4 5 6
          0 1 2 3 4 5
            0 1 2 3 4 
              0 1 2 3 
                0 1 2
                  0 1
                    0
  </code></pre>
  
  <p>How would I go about it?
  I'm going off something like </p>
  
  <pre><code>for y in range(10):
      print
      i = ?
      for x in range(i):
          print x,
          i = i - 1
  </code></pre>
  
  <p>to update the range, but I'm not sure how to write it.</p>
  
  <p>OR should I keep range the same and somehow replace each integer with a space?</p>
