写一段python脚本，用blender做一个自行车的模型

当然，我可以帮助您回答这个问题。以下是一个简单的Python脚本来创建Blender中的自行车模型：

import bpy

# 创建主场景
scene = bpy.context.scene

# 创建一个轮轴
bpy.ops.mesh.primitive_cylinder_add(radius=0.1, depth=2, location=(-1,0,0))

# 创建两个车轮，旋转90度使它们放置在轴上
wheel1 = bpy.ops.mesh.primitive_torus_add(major_radius=0.25, minor_radius=0.1, location=(-1,1,0))
bpy.context.object.rotation_euler[0] = 1.5708
wheel2 = bpy.ops.mesh.primitive_torus_add(major_radius=0.25, minor_radius=0.1, location=(-1,-1,0))
bpy.context.object.rotation_euler[0] = 1.5708

# 使用三角形面创建车架并将其绕x轴旋转45度
bpy.ops.mesh.primitive_cube_add(location=(0,0,0))
bpy.ops.object.mode_set(mode='EDIT')
bpy.ops.mesh.select_all(action='SELECT')
bpy.ops.mesh.tris_convert_to_quads()
bpy.ops.mesh.subdivide(number_cuts=1, smoothness=0.5)
bpy.ops.object.mode_set(mode='OBJECT')
frame = bpy.context.object
frame.rotation_euler[0] = 0.7854
frame.scale = (2, 0.5, 1)

# 将车轮和车架组合在一起
bpy.ops.object.select_all(action='DESELECT')
scene.objects.active = frame
frame.select = True
scene.objects.active = bpy.data.objects[wheel1['object']]
bpy.data.objects[wheel1['object']].select = True
scene.objects.active = bpy.data.objects[wheel2['object']]
bpy.data.objects[wheel2['object']].select = True
bpy.ops.object.join()
bpy.ops.object.origin_set(type='ORIGIN_GEOMETRY')

现在您可以运行此脚本并在Blender中查看结果。享受您的新自行车模型！
