you can make it a LOT easier of you just stay in pymel and skip maya.cmds.
here is an example of what you’re doing:
import pymel.core as pm
# make pynodes out of each locator or transform
loc1=pm.PyNode('locator1')
loc2=pm.PyNode('locator2')
loc3=pm.PyNode('locator3')
# get the World space position of each locator# each of these returns a Point
pt1=loc1.getTranslation(space='world')
pt2=loc2.getTranslation(space='world')
pt3=loc3.getTranslation(space='world')
# to get vectors subtract one point from another# returns a Vector
vec1=pt2 - pt1
vec2=pt3 - pt1
# .cross() is a method on any vector
cross = vec1.cross(vec2).normal() # add .normal() to normalize
