title: How to find sum of elements of a list, within a list of strings and numbers Python
body: <pre><code>list1 = [['hello',3],['bye',4].....]
  </code></pre>
  
  <p>I need to find just the sum of the numbers, 3 + 4 = 7 in this case, for an undefined number of item in the list all structured like this</p>
  
  <p>I don't know how to call a spisific element from the sublists from every sublist for a sum command. I have tryed the following but what do I put in the first brackets? Or is there a better way to write this?</p>
  
  <pre><code>sum(list1[][1])
  </code></pre>
  
  <p>Thanks!!</p>
