Important ones (for Raising):
- TypeError
- ValueError

Declarign your own Exception if you dont need to override anything:
class Secret(Exception):
    pass

Sending messages: raise MyException("My hovercraft is full of eels")

class ValidationError(Exception): # basically inherit from Exception. Or another one.
    def __init__(self, message, errors):

        # Call the base class constructor with the parameters it needs
        super(ValidationError, self).__init__(message)

        # Now for your custom code...
        self.errors = errors
        
        
Diagnosing errors:
except Exception as e:
    template = "An exception of type {0} occurred. Arguments:\n{1!r}"
    message = template.format(type(e).__name__, e.args)
    print(message)
