title: Differences between data attributes and method attributes
body: <p>What is a method attribute, and a data attribute? What the difference between them and what they have in common?</p>
  
  <p>I was reading python 2.7.9 (<a href="https://docs.python.org/2/tutorial/classes.html#random-remarks" rel="noreferrer">https://docs.python.org/2/tutorial/classes.html#random-remarks</a>) and suddenly  both became hard to understand.
  I'll appreciate some light over it.</p>
