you should do some other check, e.g. "if x in Color:".
So you don't think it's important to have an easy way to take user input that's supposed to be a Color name and either return a Color or raise a ValueError?
I don't believe that's what he said:
The name lookup is only relevant if you already know that you have a valid name of an enum in the class [...]
User input should qualify, and using getattr(EnumClass, user_input) will get you an AttributeError instead of a ValueError if user_input is not valid, but surely you don't mind that small difference. ;) -- ~Ethan~
