DELETE METHOD

• We pass id and mention that id_ is of type integer,
• we check whether or not id_ exists in the database, if exists, delete the data and provide a response that the data is deleted
• else we provide the error message.

In this way we can validate our data, we can use custom validators in the pydantic model too, like if we require to accept the name that must contain space then you can specify a validator for that,
