How to declare custom exceptions in modern Python?
To override something or pass extra arguments to the exception we do like this in modern python:
class ValidationError(Exception): def __init__(self, message, errors): super(ValidationError, self).__init__(message) self.errors = errors
That way we could pass dictionary of error messages to the second parameter, and get to it later on when needed.
