Freeze the objects

Report a typo

Suppose you've written a program that processes sensitive information. The important thing here is to make sure that the attributes of your class objects don't get changed after the initialization, so you decide to use frozen data classes. What is the correct way to do that?

Select one option from the list

@dataclass
class NewClass:
     name: str
     id: int

@dataclass(frozen=True)
class NewClass:
     name: str
     id: int

@dataclass
class NewClass:
     name: str
     id : int
     frozen=True

@dataclass(freeze=True)
class NewClass:
     name: str
     id: int
