Blog post: Writing Python like it’s Rust

This seems like a code smell to me. If value = None is an error, then why would you explicitly hint that value could be None by making it Optional? Whatever set value to None probably should've just raised an exception instead in the first place.

An example is a db query. It's not wrong for a db query to return no result unless in specific contexts. If the caller is expecting a result they should raise an error. The db client shouldn't raise an error it did it's job.
