[Tutor] exercise problem

[Roelof Wobben]

Hello, 
 
I have this exercise:
 
Lists can be used to represent mathematical vectors. In this exercise and 
several that follow you will write functions to perform standard operations on 
vectors. Create a file named vectors.py and write Python code to make the 
doctests for each function pass.
Write a function add_vectors(u, v) that takes two lists of numbers of the same 
length, and returns a new list containing the sums of the corresponding 
elements of each.


def add_vectors(u, v):
    """
      >>> add_vectors([1, 0], [1, 1])
      [2, 1]
      >>> add_vectors([1, 2], [1, 4])
      [2, 6]
      >>> add_vectors([1, 2, 1], [1, 4, 3])
      [2, 6, 4]
      >>> add_vectors([11, 0, -4, 5], [2, -4, 17, 0])
      [13, -4, 13, 5]
    """

add_vectors should pass the doctests above

 

I think that u is the name of the new list and v is the number which represent 
the number which must be eveluated.

 

Is this right or do I mis understood the exercise ?
