i would like to have this eslint rule for python

Desired solution

Not sure how practical or even possible it would be. In contrast to TypeScript, Python doesn't have an explicit export keyword. As such any module level variable could theoretically be used in another module without pylint knowing about it.

It might be possible (although still difficult) on a function scope bases, but then how often would do you annotate function variables with Final? At least from my experience, this isn't something I normally do.

To be honest I rarely used it either but only because I forgot it exists. Now that I remember it I see no reason not to use it as often as I use const in typescript

Please do by all means. I just don't think a pylint check would be worth it. Especially considering the required effort to get it to work. Just to give you an example, the somewhat related check undefined-variable is one of the most complex checks we have currently. So many corner cases to consider (and potentially miss).
