Thanks!

(At some point, the constants could be converted to Final strings that are assigned the actual value, but that can wait for another PR.)

Thanks!
Do you mean for me to pack them in Final? I was just taking an example from other packages, so I did it the way it was)

The current gold standard for constants is to use Final and the actual constant value (if it is relevant) or use Final with the type if the constant value is not really relevant:

ANSWER_QUESTION_OF_LIFE: Final = 42
SOME_RANDOM_CONSTANT: Final[int]

We'd certainly appreciate a PR changing the flask-cors constants accordingly.

@srittau Thanks for the explanation, I'll try to update soon!)
