title: Sum a sequence of numbers
body: <p>Given: Two positive integers a and b (a
  
  <p>Return: The sum of all odd integers from a through b, inclusively.</p>
  
  <pre><code>    #My code: 
      a = 100
      b = 200
      for i in range(a,b):
          if i%2 == 1:
              print i
  </code></pre>
  
  <p>At the moment it's just showing a drop down list of all the odd integers. I do not know how to affix a "range" to this properly, if need be. How can I add on to my code above to get the sum of all the odd integers? </p>
  
  <p>Thanks</p>
