What are some examples of using enums in programming?

Enums, or enumerations, are a way to define a set of named constants. For example, in Python, you can define an enum for days of the week.

Can you show me a code example of that?

Sure! Here's a simple example in Python:

from enum import Enum

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

This defines an enum called Day with constants for each day.

How would I use this enum in a function?

You can use the enum in a function like this:

def is_weekend(day):
    return day in (Day.SATURDAY, Day.SUNDAY)

This function checks if the given day is a weekend.

Are there enums in other programming languages too?

Yes, enums are available in many programming languages, including Java, C#, and Swift, each with its own syntax.
