A property should always encapsulate one or more fields, and should never do any heavy lifting or validation. If you need a property such a UserName or Password to have validation, change their type from strings to Value Objects. There is an unspoken contract between a class-creator and the consumer.
An @property is typically used to store a seemingly public argument (e.g. name) into a private attribute (e.g. _name) through getters and setters, while dataclasses generate the init() method for you.

2 In str's answer, value 'undefined' will be returned instead of the set default value if the property is undefined. This sometimes can cause bugs. The following will make sure the defaultVal will always be returned when either the property or the object is undefined.
The only reason for this answer is to include the property in the representation - because the property's backing store (_driver) is already included in comparison tests and equality tests and so on.
You're polluting an object by trying to set a property against it that does not exist
