Python - How to get Enum value by index-CodePudding

I have an Enum of days_of_the week in Python:

class days_of_the_week(str, Enum):
  monday = 'monday'
  tuesday = 'tuesday'
  wednesday = 'wednesday'
  thursday = 'thursday'
  friday = 'friday'
  saturday = 'saturday'
  sunday = 'sunday'

I want to access the value using the index.

I've tried:

days_of_the_week.value[index]

days_of_the_week[index].value

days_of_the_week.values()[index]

and so on... But everything I tried didn't returned me the value of enum (eg. days_of_the_week[1] >>> 'tuesday')

Is there a way?

CodePudding user response：

Those are simply string constants. They do not have an "index" and cannot be referred to that way.

However, you don't need to write that at all. Python provides it.

>>> import calendar
>>> list(calendar.day_name)
['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
>>> calendar.day_name[5]
'Saturday'
>>>

IIUC, you want to do:

from enum import Enum

class days_of_the_week(Enum):
    monday = 0
    tuesday = 1
    wednesday = 2
    thursday = 3
    friday = 4
    saturday = 5
    sunday = 6

>>> days_of_the_week(1).name
'tuesday'
