Enum class in python is callable, and you can define enum via functional way like below.
Example
Color = Enum('Color', 'RED GREEN BLUE')
enumFunctionApi1.py
from enum import Enum
Color = Enum('Color', 'RED GREEN BLUE')
print(list(Color))
print(Color['RED'].name, ' -> ', Color['RED'].value)
print(Color['GREEN'].name, ' -> ', Color['GREEN'].value)
print(Color['BLUE'].name, ' -> ', Color['BLUE'].value)
Output
[<Color.RED: 1>, <Color.GREEN: 2>, <Color.BLUE: 3>] RED -> 1 GREEN -> 2 BLUE -> 3
Color = Enum('Color', 'RED GREEN BLUE')
First argument to the enum is the name of enumeration.
Second argument is the source of enumeration member names.
Second argument can be a whitespace-separated string of names, a sequence of names, a sequence of 2-tuples with key/value pairs, or a mapping (e.g. dictionary) of names to values.
Example
Color = Enum('Color', [("RED", 20), ("GREEN", 21), ("BLUE", 45)])
Find the below working application.
enumFunctionApi2.py
from enum import Enum
Color = Enum('Color', [("RED", 20), ("GREEN", 21), ("BLUE", 45)])
print(list(Color))
print(Color['RED'].name, ' -> ', Color['RED'].value)
print(Color['GREEN'].name, ' -> ', Color['GREEN'].value)
print(Color['BLUE'].name, ' -> ', Color['BLUE'].value)
Output
[<Color.RED: 20>, <Color.GREEN: 21>, <Color.BLUE: 45>] RED -> 20 GREEN -> 21 BLUE -> 45
