title: When creating a new list (from data in two separate source lists) - having difficulty adding source data correctly. (Python)
body: <p>I'm trying to add together two lists and create a third list.</p>
  
  <p>My first list does not have values for each list element.</p>
  
  <p>So I only want to create a third list with the summation of list elements in list 1 and 2 if there are values in list one.</p>
  
  <p>This part works okay - However, when I try to add the values together - it doesn't keep the values from list 1 and 2.</p>
  
  <p><em>(Please see desired output below for disambiguation)</em></p>
  
  <p>Here is the code:</p>
  
  <pre><code>z=0
  for i, val in enumerate(okay_to_gl):
      if val is not None:
          for x, val2 in enumerate(okay_to_zn):
              if x == i:
                  print(val)
                  print(val2)
                  output_array_1 = val[z]+val2[z]
                  z = z + 1
                  print(output_array_1)
  </code></pre>
  
  <p>This is the output:</p>
  
  <p><img src="https://i.stack.imgur.com/1LqdN.jpg" alt="enter image description here"></p>
  
  <p>val = OK, val2=to ZA, so i want output_array[0] = OKto ZA</p>
  
  <p>So the desired output would be:</p>
  
  <p>OK</p>
  
  <p>toZA</p>
  
  <p>OKtoZA ... and so fourth.</p>
  
  <p>SO output_array_1 =(val+val2,val+val2,val+val2) where val and val2 are passed from their values during the enumerate iteration of the list.</p>
