blender python で、Boolean モディファイア による objectの差分作成

import bpy
import copy

import sys
from mathutils import Vector

def main():
    #全object削除
    remove_all_obj()

    bpy.ops.mesh.primitive_cube_add()
    bpy.ops.mesh.primitive_cube_add(location = (1,1,1))
    boolean("Cube")

    boolean = bpy.context.object.modifiers["Boolean"]
    boolean.operation = 'DIFFERENCE'
    boolean.object = bpy.data.objects[obj]
    bpy.ops.object.modifier_apply(modifier="Boolean")
