title: How to subtract two lists in python
body: <p>I can't figure out how to make a function in python that can calculate this:</p>
  
  <pre><code>List1=[3,5,6]
  List2=[3,7,2]
  </code></pre>
  
  <p>and the result should be a new list that substracts List2 from List1, <code>List3=[0,-2,4]</code>!
  I know, that I somehow have to use the zip-function. By doing that I get:
  <code>([(3,3), (5,7), (6,2)])</code>, but I don't know what to do now?</p>
