Create a IS_NOT_EMAIL() validator :
class IS_NOT_EMAIL:
def __init__(self, error_message='You can\'t use email as username'):
self.e = error_message
def __call__(self, value):
if not IS_EMAIL()(value)[1]:
return (value, self.e)
return (value, None)
Base on this!!
I wonder why we don't set flag on validators for "reverse validation" when
apply, for instance : IS_EMAIL(..., *complement=True*) will return an error
if input is email... This is use in python petl project :

Thanks.
