Well, you can learn about Python's OO nature by writing class to handle
this:

    class vector:
	def __init__(self, x=[]):		# vector([...])
	    self.array = x[:]
	    self.n = len(x)

	def __repr__(self):
	    return `self.array`

	def __add__(self, other):
	    for a, b in map(None, self.array, other.array):
		out.append(a + b)
	    return vector(out)

>>> a = vector([1,2])
>>> b = vector([2,3])
>>> a+b
[3, 5]
