Python recursion simple error

Hi,
I am confused as to why this code is not working. I believe it has to do with the fact that Rhino draws circles with radii rather than diameter. I am simply trying a simple recursion where circles are scaled by half the diameter and moved by half of the diameter. Attached is an image I made in processing.

import rhinoscriptsyntax as rs
import Rhino.Geometry as rg

a = []

x = 2
y = 0
p1 = rs.coerce3dpoint([x,y,0]) 


def recursiveCircle(p1, r, num): #input variables
        r = 3
        print r/2
        p2 = rs.AddPoint(x + r, 0, 0)
        a.append(p2)
        cir1 = rs.AddCircle(p1, r)
        a.append(cir1)  

        if (num > 1):
             #counter
            
            #recursive function ; needs to be diameter
            recursiveCircle(p1 + rg.Point3d(x + r*.5, y, 0), r*.5, num-1) 
            
 
      
recursiveCircle(p1, r, 2) #input parameters

I am sure that I am missing something silly. I just don't totally understand the hierarchy of the recursive functions.
1. declare the function with the variables
2. call the function outside the function with parameters
3. pass the outside parameters through the insider recursive function.

Thank you for the help!
Erik
