title: Iterating through multiple lists with same index position in python
body: <p>I am new to python and I was just trying some list manipulations. I have three lists</p>
  
  <pre><code>A = [10,20,30,40,50,60]
  B = [22,44,66,88,12,10]
  C = [2,4,6,8,10,20]
  </code></pre>
  
  <p>I want to iterate over these three lists and for each value of C I want to add half of that value to the corresponding values of A and B. 
  For example for the 1st iteration - 
  half = 2/2= 1
  So A = 10 + 1 and B = 22+1
  So the final lists should look something like this</p>
  
  <pre><code>A = [11,22,33,44,55,70]
  B = [23,46,69,92,17,20]
  C = [2,4,6,8,10,20]
  </code></pre>
