Class attributes are shared across all instances, while instance attributes are unique to each object. Python's attribute resolution follows a clear lookup chain: it checks the instance's __dict__ first, then the class's __dict__ , and finally the base classes according to the Method Resolution Order (MRO). This mechanism, known as the "descriptor protocol," governs everything from method binding to property access. This mechanism, known as the "descriptor protocol," governs

Beyond basic enumerations, Python supports IntEnum (for enumeration members that also behave as integers), Flag (for bitwise operations), and automatic value assignment. Enums also participate in the type system: a function expecting an Enum type cannot accept arbitrary integers or strings, providing compile-time safety. known as the "descriptor protocol
