How to use glob.glob function with pre-define path?

问题

I want to use my pre-define path in glob function like code:

import glob
import os
list_of_files = glob.glob('/Jaymin/MAC Report/*.txt')
latest_file= max(list_of_files, key=os.path.getctime)

but instead of this I have path stored in my variable like:

My_path=/Jaymin/MAC Report

so how can I replace my_path variable to the path ? like:

list_of_files = glob.glob(MY_PATH'/*.txt')
