Because this way, you get a function, not a method. I'd say "read  
something about descriptors" but...

Nicolas Bourbaki [a collective of french mathematicians writing under that  
alias] said on a book about set theory: Any school boy can understand all  
of this with a minimum of effort, but for truly understanding what we are  
talking about, around four years of prior training on mathematics may be  
required. (I can't find the exact citation).

I suggest first learn to use Python and then try to understand how it does  
what it does, along the way, and looking for answers when you have a  
question.
