I am working on this code from the post: How can I run blender from command line or a python script without opening a GUI?

I am trying to open a blend file and have a script run in that blend file to do some actions.

but I get error while running this code from the above post

import bpy
import subprocess

f_path = 'C:/Users/naman/Desktop/test.blend'

code = """
import bpy

for obj in bpy.data.objects:

output = subprocess.check_output( f"blender '{f_path}' -b --python-expr '{code}' ", shell = 

Error in the Blender enter image description here
