Let's say one file has 10 global constants that I want to import into another file.

Instead of doing the following, is there an easier way to import all global constants without doing something like: from file_one.py import *. I do not want it to import the entire file, only global variables.

from file_one.py import DEFINE1, DEFINE2, DEFINE3, ..............
