Blender - Light Radius Size of Multiple Lights to 0.03

import bpy

# Get the selected objects
selected_objects = bpy.context.selected_objects

# Iterate through the selected objects
for obj in selected_objects:
    # Check if the object is a light and is either POINT or SPOT type
    if obj.type == 'LIGHT' and obj.data.type in {'POINT', 'SPOT'}:
        # Set the radius size (shadow_soft_size) to exactly 0.03
        obj.data.shadow_soft_size = 0.03

# Update the scene to reflect the changes
bpy.context.view_layer.update()
