Well, the subject says it almost all: I'd like to write a small Vector
class for arbitrary-dimensional vectors.
I am wondering what would be the most efficient and/or most elegant
way to compute the length of such a Vector?
Right now, I've got
def length(self): # x.length() = || x ||
total = 0.0
for k in range(len(self._coords)):
d = self._coords[k]
total += d*d
However, that seems a bit awkward to me (at least in Python ;-) ).
I know there is the reduce() function, but I can't seem to find a way
to apply that to the case here (at least, not without jumping through
too many hoops).
I have also googled a bit, but found nothing really elegant.
