Moving object via loop prints same location every count

Question

I am trying to step an object by a small increment via for loop; then return the XY location of each step. Ultimately this will be written to a text file but for now I'm just trying to get the console to print correctly.

The result is the same object XY location from where it started at the beginning of the script, rather than the incremental moves. Is there anything obvious to adjust in the code?

Printed Result

Python Script:

import bpy

objPart = bpy.context.scene.objects["L FRONT LEG bacci mm"]
objTool = bpy.context.scene.objects["Cylinder"]
objDriver = bpy.data.objects["Plane"]

partLength = objPart.dimensions[0]
passWidth = 1.5
passQty = round(partLength / passWidth)
passRes = 180
stepCount = passQty * passRes
stepWidth = passWidth / passRes

def moveIt():
    objDriver.location.x = objDriver.location.x + stepWidth
    print(objTool.matrix_world.translation)

for s in range(1, stepCount):
    moveIt()

When I run the "moveIt()" function manually one at a time, I get the numbers I want. Which is not ideal as this will run 1000's of times to return each number

>>> operations.moveIt()
<Vector (28.3410, -59.6781, 0.0000)>

>>> operations.moveIt()
<Vector (28.2845, -59.6578, 0.0000)>

>>> operations.moveIt()
<Vector (28.3285, -59.6528, 0.0000)>

>>> operations.moveIt()
<Vector (28.2939, -59.6368, 0.0000)>

>>> operations.moveIt()
<Vector (28.3251, -59.6224, 0.0000)>

>>> operations.moveIt()
<Vector (28.3353, -59.6290, 0.0000)>
