Create Enum constant in Flask/Python

Question

Hi I would like to have a file that contain an enum list of all the items I will be using in my configuration. E.G

{
  "SUCCESS": 1,
  "FAILED": 1,
  "PENDING": 1,
}

I wanted something like in Laravel where in you will only place all your Enum in one of the files. In Laravel I can place this inside the folder config and file list_item e.g

return [
  "SUCCESS": 1,
  "FAILED": 1,
  "PENDING": 1,
]

so if I reference this in laravel its like config('config.list_item') and this will contain the array that I defined in my list_item file. Is there a way to achieve the same approach in Python/Flask? The only way I can think of is creating a file and inside it I will be defining a function like the example below

def StatusEnum():
    return {
       "SUCCESS": 1,
       "FAILED": 1,
       "PENDING": 1,
    }

and referencing it with StatusEnum() but I want to have a cleaner way to this.

So basically I want a cleaner and best approach to have a file that contains all my Enum list. I wan't to know how to do this in python/flask.

@LelandBarton edited my question. I wan't something like how Laravel loads and store all config/constants variable (Enum) — MadzQuestioning

You can use configparser from stand library.

#config.cfg
[status]
FAILED = 0
SUCCESS = 1
PENDING = 1

# python source code 
import configparser
config = configparser.ConfigParser()
config.read("config.cfg")
config.getint("status", "FAILED")

Or just place a dict variable in your configuration file. Import it where you want to use it.

# config.py
status = {"FAILED": 0, "SUCCESS": 1, "PENDING": 2}

from config import status

print(status["FAILED"])

It seems this is a good idea almost the same with Laravel. I'll accept this as the answer thanks
