Yesterday my exercise got downvoted, probably because its point was unclear. I'd like to try again with this reworked exercise. Hope you'll like this one better.

• Solution
• Explanation: “User-defined classes have __eq__() and __hash__() methods by default (inherited from the object class); with them, all objects compare unequal (except with themselves) and x.__hash__() returns an appropriate value such that x == y implies both that x is y and hash(x) == hash(y).”
