[blender] Is this python function correct for finding distance?

    def getDistance(self,p1,p2):

        ret= ((p2.x-p1.x)**2) + ((p2.y-p1.y)**2) + ((p2.z-p1.z)**2)
        ret=math.sqrt(ret)

        return ret

Its a blender script function. It takes the vertices point of two 3d vertices, to calculate their distance to each other.

Yeah, it does resemble a Pythagoras :-)

I'm sure Blender has function for this that makes use of more advanced features.

Or do:

(p2-p1).length

which uses Blender's vector maths.
(which is natively implemented, so should be faster)

I'll try using the referenced algo.
