Creating objects with VizLayers and returning creates duplicates....?

Code:
import viz
import vizact
import vizshape
from math import sin, cos, tan, pi

viz.go()

def createCube(cubeSize=2):
	viz.startLayer(viz.QUADS) 
	#front
	viz.vertex(0,0,0)
	viz.vertex(cubeSize,0,0) 
	viz.vertex(cubeSize,cubeSize,0) 
	viz.vertex(0,cubeSize,0) 
	
	#bottom
	viz.vertexColor(viz.RED)
	viz.vertex(0,0,0)
	viz.vertex(cubeSize,0,0)
	viz.vertex(cubeSize,0,cubeSize)
	viz.vertex(0,0,cubeSize)
	
	#left
	viz.vertexColor(viz.YELLOW)
	viz.vertex(0,0,0)
	viz.vertex(0,cubeSize,0)
	viz.vertex(0,cubeSize,cubeSize)
	viz.vertex(0,0,cubeSize)
	
	#right
	viz.vertexColor(viz.BLUE)
	viz.vertex(cubeSize,0,0)
	viz.vertex(cubeSize,cubeSize,0)
	viz.vertex(cubeSize,cubeSize,cubeSize)
	viz.vertex(cubeSize,0,cubeSize)
	
	#back
	viz.vertexColor(viz.GRAY)
	viz.vertex(0,0,cubeSize)
	viz.vertex(cubeSize,0,cubeSize) 
	viz.vertex(cubeSize,cubeSize,cubeSize) 
	viz.vertex(0,cubeSize,cubeSize) 
	
	#top
	viz.vertexColor(viz.GREEN)
	viz.vertex(0,cubeSize,0)
	viz.vertex(cubeSize,cubeSize,0)
	viz.vertex(cubeSize,cubeSize,cubeSize)
	viz.vertex(0,cubeSize,cubeSize)
	cube = viz.endLayer() 

	#rotate = vizact.spin(x=0,y=45,z=0,speed=90)
	#myQuad.addAction(rotate)
	return cube

def createCylinder(radius=3,height=5,detail=10):
	angleIncrement = 360/detail;
	
	#create a group of everything
	cylinder = viz.addGroup()
	
	viz.startLayer(viz.POLYGON)
	#viz.vertex(0,0,0)
	for i in range(detail):
		x = radius * cos(((i*angleIncrement)*pi)/180)
		y = radius * sin(((i*angleIncrement)*pi)/180)
#		x = radius * cos(i*angleIncrement)
#		y = radius * sin(i*angleIncrement)
		print("x is " + str(x))
		print("y is " + str(y))
		viz.normal(x,0,y)
		viz.vertex(x,0,y)
	bottom = viz.endLayer(parent=cylinder)
	
	
#make the top
	viz.startLayer(viz.POLYGON)
	#viz.vertex(0,height,0)
	for i in range(detail):
		x = radius * cos(((i*angleIncrement)*pi)/180)
		y = radius * sin(((i*angleIncrement)*pi)/180)
		viz.vertex(x,height,y)
	top = viz.endLayer(parent=cylinder)
	
	#now make all the sides
	viz.startLayer(viz.QUAD_STRIP)
	viz.vertexColor(viz.GRAY)
	for i in range(detail):
		x = radius * cos(((i*angleIncrement)*pi)/180)
		y = radius * sin(((i*angleIncrement)*pi)/180)
		viz.vertex(x,0,y)
		viz.vertex(x,height,y)
	
	x = radius * cos(((0*angleIncrement)*pi)/180)
	y = radius * sin(((0*angleIncrement)*pi)/180)
	viz.vertex(x,0,y)
	viz.vertex(x,height,y)
	sides = viz.endLayer(parent=cylinder)

	return cylinder

box1 = createCube(9);
box1.setPosition(0,5,0)

head = createCube(2)
head.addParent(box1)
head.setEuler(180,0,0)
head.setPosition(3,8,0)

arm1 = createCylinder(1,9,20)
arm1.addParent(box1)
arm1.setPosition(-3,-2,3)
arm1.setEuler(0,0,-20)

arm2 = createCylinder(1,9,20)
arm2.addParent(box1)
arm2.setPosition(11,-2,3)
arm2.setEuler(0,0,20)
I am creating objects and assigning them to values through function return values. For some reason, everything I create is duplicated somehow and I'm at a loss. Am I already placing the object, then placing it again by assigning it to a value? New to Python and WorldViz.

Try using setParent instead of addParent. When you use addParent the object will still retain its current parents.
