将常量从外部文件导入python

Question

我想从外部文件导入一个常量。我在一个目录中有两个文件。 constants.py个文件：

SOME_CONSTANT = 'something'

并将其导入settings.py

import constants

someVariable = constants.SOME_CONSTANT

但是pylint写下Module 'constants' has no 'SOME_CONSTANT' member

Answer 1

不能真正说出如何制作常量，但是理想情况下，您希望将它们存储在类中。

#Constants.Py
class Province:
    CITY = 'Toronto'

#Settings.Py
from Constants import Province
someVariable = Province.CITY
>>> 'Toronto'
