写一段python脚本，用blender做一个车的模型

当然，我很乐意回答你的问题。以下是你需要的 Python 脚本：

import bpy

# 删除所有默认场景中的对象
bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete()

# 创建车的主体
bpy.ops.mesh.primitive_cube_add(location=(0,0,0))
body = bpy.context.object
body.dimensions = (2, 1, 0.5)
body.name = "Car Body"

# 创建轮子
bpy.ops.mesh.primitive_cylinder_add(location=(-0.8,-0.5,-0.25))
wheel1 = bpy.context.object
wheel1.dimensions = (0.4, 0.4, 0.4)
wheel1.name = "Wheel1"

bpy.ops.mesh.primitive_cylinder_add(location=(0.8,-0.5,-0.25))
wheel2 = bpy.context.object
wheel2.dimensions = (0.4, 0.4, 0.4)
wheel2.name = "Wheel2"

bpy.ops.mesh.primitive_cylinder_add(location=(-0.8,0.5,-0.25))
wheel3 = bpy.context.object
wheel3.dimensions = (0.4, 0.4, 0.4)
wheel3.name = "Wheel3"

bpy.ops.mesh.primitive_cylinder_add(location=(0.8,0.5,-0.25))
wheel4 = bpy.context.object
wheel4.dimensions = (0.4, 0.4, 0.4)
wheel4.name = "Wheel4"

# 组合车的部件
bpy.ops.object.select_all(action='DESELECT')
body.select_set(True)
wheel1.select_set(True)
wheel2.select_set(True)
wheel3.select_set(True)
wheel4.select_set(True)
bpy.ops.object.parent_set(type='OBJECT', keep_transform=True)

运行该脚本，您将获得一个简单的车模型，包括一个立方体作为车身，四个圆柱体作为轮子。如果您希望模型具有更多的细节和精度，则可以通过 Blender 的其他功能来实现。
