Dear Tutors,
I noticed that when you use a property to represent a mutable
value, I you try to use its methods, it will directly change the value
returned. I know this happens because I'm not really assigning it to

as a "wall" between e

What does the documentation say about join? What part of that do you not
understand?

pickle.dump(object, f, 2)
# unpickle object
