Python enum Module

RED = 1
GREEN = 2
BLUE = 3
print(Color.RED.name)
print(Color.RED.value)

Definition and Usage
The enum module supports enumerations, which are sets of symbolic names bound to unique, constant values.
Use it to define readable constants, compare by identity, and iterate over named values cleanly.

| EnumType | Metaclass for Enum and Flag types. |
