title: line 60, in make_tuple return tuple(l) TypeError: iter() returned non-iterator of type 'Vector'
body: <p>I am new to Vectors and making classes. I am trying to construct my own vector class but when i pass it through my code which is:</p>
  
  <p>position += heading*distance_moved</p>
  
  <p>where position and heading are both vectors. heading is normalized. my goal is to repeat my code until position = destination.
  What is wrong with this class?</p>
  
  <p>import math</p>
