Are all hashable data types in python with unique elements?

Question

I am trying to mark out the difference between various data types to determine which one uses hash values at the backend. Please clarify. Thanks.

Answer 1

Hashable data types: int, float, str, tuple, and NoneType.
Unhashable data types: dict, list, and set.

Unhashable data types are all mutable in nature, while these five hashable data types are all immutable
