Make sure random_state is a list before indexed assignment #968

Issue: #722

Currently, a mypy error occurs because we attempt to assign to random_state[1] when random_state has type
Union[list[Any], tuple[Any]]. Tuples are immutable so this is a type error.

We fix this by making random_state into a list before doing indexed assignment on it. This tells mypy that random_state is definitely a list and cannot be a tuple.

This might be a case for cast as opposed to a computation. I'm surprised isinstance(random_state, (list, tuple)) isn't alleviating this.

yeah just trick mypy with the cast rather than at execution time actually changing the type to list

It's because random_state could be a tuple, in which case indexed assignment isn't possible.

Is there any possibility that random_state is a tuple while random_state[1] is a list? If this will never happen we can safely cast here, or change the line 1558 conditional to if isinstance(random_state[1], list) and isinstance(random_state, list):

Though, if this ever did happen in the past it would've thrown a runtime error.

I just committed this solution since it avoids casting

You might need to rebase... looking at the commits in this PR: some of them aren't probably related to the work you did on this PR itself
