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

return sqrt(total)

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.

Any ideas?

Best regards,

Gabriel.
