best way to call instance variable from other places/directory?

In my project I have a settings.py which contains a class and a constructor. (It contains more than 70 instance variables.)

I know I can call that variable with the help of by creating class object.value, but I have more than 25 folders. Is calling with help of a class name the best approach? Will it slow performance?

My directory structure:.

├───A
│   ├───.idea
│   │   └───inspectionProfiles
│   ├───abrest
│   │   └───app
│   │       ├───config
│   │       │   └───settings.py
                └───log_config.py
│   │       ├───handle
│   │       └───utils
│   ├───utils
│         └───test.py

a) setting.py

class BaseConfig:
    def __init__(self):
        self.A = '/api'
        self.B = False
        self.C = False
        self.D = "0.0.0.0"
        self.E = "localhost"
        self.F = 8000
        self.G = "test"
        self.H = 'tokens'
        self.I = 'default-secret'

b) How can I call inside other directory without doing class name (because I believe it is not the best practice if there are more than 100 variables).

For example, I am calling variable in:

test.py

from abrest.app.config.settings import BaseConfig

print(BaseConfig().B)

Output:

PycharmProjects/A/utils/test.py False Is there any way to call it from config.variable_name OR config.log_config_variable? (And also I need suggestions on how it will affect performance.)

If all the attributes are constant for all the instances, its better to create those as class variables instead of instance variables. For example I would write the setting class as :

class Config:
  NAME = 'settings'
  DEBUG = True
  BASE_DIR = '~/config/'

and access it as Config.NAME etc, so that I don't have to create an instance. Otherwise you can use the attributes directly by importing like this,

from Config import *
