Python中配置变量的最佳实践

Question

So recently my programs have become more complex, and are starting to require more configuration. I've been doing the following, however it feels wrong...

class config:
    delay = 1.3
    files = "path/to/stuff"
    name = "test"

dostuff(config.name) #etc...

I've never been a fan of the ALL_CAPS_VARIABLE method, and was wondering if there is an "official" way to do this, and if there is anything wrong with my current method.

Answer 1

I recommend use of python-decouple . This library allow separate code from configurations(data).

UPDATE:

Brief explanation of usage of this library:

Simply create a .env text file on your repository's root directory in the form:

DEBUG=True
TEMPLATE_DEBUG=True
EMAIL_PORT=405
SECRET_KEY=ARANDOMSECRETKEY
DATABASE_URL=mysql://myuser:mypassword@myhost/mydatabase
PERCENTILE=90%
#COMMENTED=42

OBS: put *.env in your .gitignore

On your python code, can be used in this way:

from decouple import config

SECRET_KEY = config('SECRET_KEY')
DEBUG = config('DEBUG', default=False, cast=bool)
EMAIL_HOST = config('EMAIL_HOST', default='localhost')
EMAIL_PORT = config('EMAIL_PORT', default=25, cast=int)
