Constant variable names in all modules/functions - python-3.x

Question

This is version 2 of my question, after the comment on v1 by Omer Dagry.
What's the best way to ensure that constants are available throughout my code?
I've created this constants.ini file that I want to be able to use in any module I create to ensure standard variables for certain functions.
; dd_config.ini
[DEBUG_TYPE]
DEBUG_SUBSTR = -1
DEBUG_START = 0
DEBUG_OS = 1
DEBUG_GENERAL = 2
DEBUG_END = 3
I have re-ordered program 1 so that it populates dd_con before importing dd_debug_exception:
from configparser import ConfigParser
# read the .ini file for some of the code
dd_con = ConfigParser()
dd_con.read(
"C:/Users/DD/dd_constants.ini"
)
# standard error reporting if debug needed
from test_debug_2 import dd_debug_exception
_SHORT = dd_con.get("DEBUG_STYLE", "DEBUG_SHORT")
print(_SHORT)
dd_debug_exception(0, "test", _SHORT)
Import dd_debug_exception does this:
def dd_debug_exception(debug_type,
debug_str,
debug_style: int = dd_con.get("DEBUG_TYPE",
"DEBUG_NORMAL")):
# Handle exceptions in a standard way
if debug_style == _SHORT:
print("hello")
When I try to run it I get the following error:
Traceback (most recent call last): File
"c:\Users\DD\test_config.py", line 9, in
from test_debug_2 import dd_debug_exception File "C:\Users\DD\test_debug_2.py", line 3, in
debug_style: int = dd_con.get("DEBUG_TYPE", NameError: name 'dd_con' is not defined
The import is still not recognising dd_con and therefore my standard variables.
