Question

Here’s how I am declaring constants and using them across different Python classes:

# project/constants.py
GOOD = 1
BAD = 2
AWFUL = 3

# project/question.py
from constants import AWFUL, BAD, GOOD

class Question:
    def __init__(self):
        ...

Is the above a good way to store and use contant values? I realise that after a while, the constants file can get pretty big and I could explicitly be importing 10+ of those constants in any given file.

Answer 1

why not just use

import constants

def use_my_constants():
    print constants.GOOD, constants.BAD, constants.AWFUL

From the python zen:

Namespaces are good. Lets do more of those!

EDIT: Except, when you do quote, you should include a reference and check it, because as others have pointed out, it should read:

Namespaces are one honking great idea — let’s do more of those!

This time, I actually copied it from the source: PEP 20 — The Zen of Python
