Mutable objects can't be hashed right?

  As the comment you responded to says: An object can be mutable and hashable. E.g. any custom class by default has mutable and hashable instances.

    How can you get both mutable and hashable instances at the same time?
    • detaro 7y ago
      the only requirement on a hashable instance is that it implements a proper __hash__ function. The default implementation in CPython returns the address of the memory the object is stored at, so all instances are considered unique, values play no role at all.
