How do I rotate an object.

selection_list = self.svg.selected
if len(selection_list) < 1:
    inkex.errormsg('nothing selected')
    return

# Import the python random range function
from random import randrange
# Import the inkex Transform module
from inkex import Transform

for item in selection_list:
    # Get the bounding box of the item
    # This will not work for Text objects
    item_bbox = item.bounding_box()
    # Get a random rotation value
    random_rotation_degrees = randrange(0, 360)
    # Create a Transform object
    rotate_transform = Transform()
    # Add the transform degrees and centre to the object
    rotate_transform.add_rotate(random_rotation_degrees, item_bbox.center)
    # Multiply the existing object Transform by the Rotation Transform 
    item.transform = item.transform @ rotate_transform

Really much appreciated, Thanks!
