title: Offset positive and negative numbers in two lists and get the rest in Python
body: <p>I have two lists consisting of a series of positive or negative numbers, and two lists may have unequal lengths, like this:</p>
  <pre><code>lst1 = [2, 3, 3, 5, 6, 6, 6, 8, 10]
  lst2 = [-1, -2, -2, -3, -6, -10, -11]
  </code></pre>
  <p>The result I want to get is:</p>
  <pre><code>lst_ofs = [-1, -2, 3, 5, 6, 6, 8, -11]
  </code></pre>
  <p>Positive and negative numbers with equal absolute value in the two lists are offset by quantity, is there any easy way to do this?</p>
