How to write a program that references to file, where the directory changes

Question

I'm currently working on a program that uses databases and all that kind of stuff for a friend of mine. Now while doing my basic planning of what I will need to do, I thought to myself how will I get the program to connect to the right MS Access database if I hard code the path to my own personal computer? Because ill be using pyinstaller to package the program for him.

Do I need to build the directory in a dynamic way that uses the path of the current script, and then some string manipulation of that path to get the right file? ie

import os
    
file_path = os.path.realpath(__file__)
# Using prior knowledge knowing the file name length is 7
file_path = file_path[:-7]                        
#appending the path string to point to the database
file_path = file_path + "/databases/test.accdb"   

Or will the program still someway find its way to that database?

You can use a: os.walk(...) function to locate specified name file or every database file in specified directories. Next user can choose which file is correct
