I think you'll have to use DescID for this.
The kind of code only a mother (or a C++ user) could love.

Thanks for the reply ScottA.  I've tried using the code you provided.

#Using DescID... Combine the POSITION option, with the VECTOR option. And then assign them to a variable("posX")  
  #Using DescID... Combine the SCALE option, with the VECTOR option. And then assign them to a variable("scaleY")  
  posX = c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_ABS_POSITION), c4d.DescLevel(c4d.VECTOR_X));  
  scaleY = c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_ABS_SCALE), c4d.DescLevel(c4d.VECTOR_Y));  
  
  
  #Add the position.x output port to the object node using the stuff we have in memory  
  #Add the scale.y output port to the object node using the stuff we have in memory  
  node.AddPort(c4d.GV_PORT_OUTPUT, posX)  
  node.AddPort(c4d.GV_PORT_OUTPUT, scaleY)

It works, (it creates Transformed Position .X and Transformed Scale .Y ports) but it doesn't create the port I was hoping to gain access to (Object Properties > Size > Size.Y)  Is it just not possible to create this port automatically?

Finally figured it out.

This code:
node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, (1100, 1001))

Will add Size.Y output port.

I was able to figure out the numbers by typing "print(PRIM_CUBE_LEN, VECTOR_Y)" in the console window.

However, now the xpresso node with Size.Y is yellow.

It's yellow because you are telling the node to output the size of something. But it doesn't have any inputs to look at to know what it is you want to change the size of.

It's considered better practices to use the text based ID's whenever you can:
node1out = node.AddPort(c4d.GV_PORT_OUTPUT, (PRIM_CUBE_LEN, VECTOR_Y))

Shouldn't the Size.Y be referencing the cube?

The goal of this script is to create a cube inside of a null object.  In Xpresso, I want to multiply the Size.Y of the cube by 0.5 and use the result as the Position.Y of the cube.

If I do this manually, everything works fine.

Here is my code.

import c4d

def main() :
    null = c4d.BaseObject(c4d.Onull)
    doc.InsertObject(null)

cube = c4d.BaseObject(c4d.Ocube)
    doc.InsertObject(cube,null)

xtag = c4d.BaseTag(c4d.Texpresso)
    null.InsertTag(xtag)

nodemaster = xtag.GetNodeMaster()
    print nodemaster.GetOwner().GetName()

node1 = nodemaster.CreateNode(nodemaster.GetRoot(),c4d.ID_OPERATOR_OBJECT,None,100,100)
    node1[c4d.GV_OBJECT_OBJECT_ID] = cube

node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, (c4d.PRIM_CUBE_LEN, c4d.VECTOR_Y))
    print node1.GetOperatorContainer()[c4d.GV_OBJECT_OBJECT_ID].GetName()

c4d.EventAdd()

Try this line of code without the extra parenthesis:

  
node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, c4d.PRIM_CUBE_LEN, c4d.VECTOR_Y)

Oops.
Scratch that. I just noticed that doing that removes the .Y from the node.

I'm not sure why the xpresso node isn't working properly when the Size.Y port is added.
There must be some other missing step needed to tell C4D to update the changes.
I'm afraid I'm out of ideas.

Yeah, it doesn't make sense.  When I try to do the same thing with Relative Position.Y the node works fine.

Looks to be a bug

I found that you can side step this by using a "real to vector" node.

So rather than trying to get at the sub component right away you get the entire vector package.
examples are best.

import c4d
from c4d import gui
#Welcome to the world of Python
  
  
def main() :
    xtrude = c4d.BaseObject(5116)
    xtag = c4d.BaseTag(1001149)
    
    
    doc.InsertObject(xtrude)
    xtrude.InsertTag(xtag)
    
    gv = xtag.GetNodeMaster()
    
    xtrude_node = gv.CreateNode(parent = gv.GetRoot(),id = c4d.ID_OPERATOR_OBJECT )
    xtrude_node[c4d.GV_OBJECT_OBJECT_ID] = xtrude
    mov = xtrude_node.AddPort(c4d.GV_PORT_INPUT, [c4d.EXTRUDEOBJECT_MOVE])#(c4d.EXTRUDEOBJECT_MOVE,c4d.VECTOR_Y)) ####report_bug
    
    r2v = gv.CreateNode(parent = gv.GetRoot(),id = c4d.ID_OPERATOR_REAL2VECT )
    r2v_x_in = r2v[c4d.GV_REAL2VECT_INPUT_X]
    r2v_out = r2v.GetOutPorts()[0]
  
    r2v_out.Connect(mov)
