Test your knowledge: Python Enumerations

Review

1. For this enum, what does Status.READY.name return?

   The name is the declared identifier READY. The value is a separate attribute.
2. Given class State(Enum): READY = 'ready', which expression looks up the member by value?

   Calling the enum with 'ready' returns the matching member; square-bracket lookup uses the member name.
3. What is the result of Status.READY == 'ready' for a plain Enum member with value 'ready'?

   A plain Enum member is a named enum object. Its .value may be a string, but the member does not thereby become equal to that string.
4. What order is used when iterating over an enum's canonical members?

   Enum iteration yields canonical members in definition order, not a sorted order.
5. What happens when @unique decorates an enum containing two names with the same value?

   The decorator rejects duplicate values by raising ValueError while the class is being defined.
