class Actor(object):

		self.attrs = ["name", "age", "race", "profession"]

class Citizen(Actor):
	def __init__(self, name, age, race, profession, awesomeness):
		self.awesomeness = awesomeness
		Actor.__init__(self, name, age, race, profession)
		self.addAttr("awesomeness", self.awesomeness)

a_person = Citizen('a person', 15, 'human', 'assassin', 190999)
a_person.saveAttributes('person')

this is my error:
