maya python, finding the distance between two vectors

Great little funciton for finding the distance between two points in maya.

import maya.cmds as Mc 
from math import pow,sqrt

def GetDistance(objA, objB):
	gObjA = Mc.xform(objA, q=True, t=True, ws=True)
	gObjB = Mc.xform(objB, q=True, t=True, ws=True)
	
	return sqrt(pow(gObjA[0]-gObjB[0],2)+pow(gObjA[1]-gObjB[1],2)+pow(gObjA[2]-gObjB[2],2))
