What are enumerations used for in programming?

Enumerations (enums) in programming are used to define a set of named constants that are logically related. This helps make the code more readable and safer, as instead of using arbitrary numbers or strings, understandable names can be used.

For example, in Python, you can define an enumeration for the days of the week:

from enum import Enum

class Weekday(Enum):
    MONDAY = 1
    TUESDAY = 2
    WEDNESDAY = 3
    THURSDAY = 4
    FRIDAY = 5
    SATURDAY = 6
    SUNDAY = 7

Using enum helps avoid errors related to incorrect values and improves code maintenance.
