title: Summing a tuple in a list, in python
body: <p>I know there must be a quick way to do this, but can't seem to find it.
  I need to find a way to add the items in a tuple. i was hoping for something like mytuple.sum.</p>
  
  <p>I have a list of tuples like mylist= [(1,3,5,3),(1,5,5,5),....,(1,3,2,1),(1,1,1,2)]</p>
  
  <p>and need to be able to call on it similarly to mylist[0].sum</p>
  
  <p>Thanks!</p>
