  <p>Say I have a class "Person", with an instance variable "age". Coming from Python, when writing methods for the Person class, I am used to accessing age using "self.age", however in Objective C I have noticed that both and "self.age" and "age" are accepted when referring to the instance variable (whereas in Python only the former would work).</p>
  
  <p>When it is not explicitly specified which instance's variable you mean, does it default to 'self'? And is it considered bad style not to explicitly specify self? If not, are there conventions on when to use self.age and when to use age?</p>
