There was a problem hiding this comment.
I understand that the TypeGuard does provide some help for the type checker here, but still, I think it's clearer if the len(...) == 1 check is inlined in the elif statements above, and then a cast is used inside the elif blocks. As it is, I find myself jumping up and down in the code to understand what it's doing.
It would be nice if Python type checking were smarter and didn't require either of these workarounds.
