[Python] How to filter variables for import in Python

I really need to solve my problem because one of the scripts I built, there are hundreds of variables; and in the other script, I don't want to import all variables but only specific variables using Regex; but it seems there is no way how to do.

I'll give an example, there are two scripts, the first one is load.py and the second is main.py

script_load.py

import os
from configparser import ConfigParser

file = os.path.join(os.getcwd(), 'file.txt')
fparser = ConfigParser()
fparser.read(file)
COLOUR_ONE = fparser.get("GENERAL", "Green")
COLOUR_TWO = fparser.get("GENERAL", "Red")
COLOUR_THREE = fparser.get("GENERAL", "Blue")
BUILDING_ONE = fparser.get("GENERAL", "House")
BUILDING_TWO = fparser.get("GENERAL", "School")
BUILDING_THREE = fparser.get("GENERAL", "Supermarket")


script_main.py

from script_load import r'^COLOUR.+$'

def function():
global r'^COLOUR.+$'

print(COLOUR_ONE+COLOUR_TWO+COLOUR_THREE)


As the above, I want to use a syntax like import r'^COLOUR.+$' instead of import * to filter variables as imported. However, I tested and it got error as the following output:

SyntaxError: invalid syntax
