![]() Additionally, enums can be iterated over and compared with other enum members. It allows you to represent distinct values or states in an expressive and safe way, as well as access the name and value of enum members directly. The Enum module in Python is a useful tool for creating enumeration classes. Print(my_color is Color.BLUE) # Output: True You can also access the name and value of an enum member directly: Using the enum in your code makes it more readable and less prone to errors, since you cannot pass arbitrary values to the function, only valid enum members. Here, the `print_favorite_color` function expects a `Color` enum as input. The `auto()` function assigns automatically unique and increasing integer values to the enum members, starting from 1. In this example, we have created an enumeration class named `Color` representing three different colors: RED, GREEN, and BLUE. Define your enumeration class by inheriting from `Enum`: Import the Enum class from the `enum` module:Ä¢. Defining a Typical Enumerated Type For simple cases where you just want some alternative values, you can follow this pattern: This creates an enumerated type Suit that defines symbols for the four card suits, called members. Hereâs an example of how to use an Enum class in Python:Ä¡. We covered some of the discussion around PEP 435 ( Adding an Enum type to the Python standard library ) back in 2013 when it was approved. The enum module first appeared in Python 3.4 the following year. Enums are useful when you need to represent distinct values or states in a more expressive and safe way than just using constants or plain integers. This video explains in detail how to implement an enum in Python. In Python, you can use the Enum module, which was introduced in Python 3.4, to create enumeration classes. Enums in Python Python Tutorial - YouTube. Weâll also explore some of the features that enums provide such as accessing names and values directly, iterating over them, and comparing enum members with each other. ![]() To create an enumeration, use the class syntax. The second variation of Enum that is provided is also a subclass of str. from enum import Enum class Fruit (Enum): apple 1 banana 2 orange 3 list (Fruit) , ,Within an enumeration, the members can be compared by identity, and the enumeration itself can be iterated over. ![]() To support enumerations in your Python project, import the Enum class from the enum module. An enumeration is a set of symbolic names (members) bound to unique, constant values. So enumeration is just a type for a group of constant values. Weâll look at how to create enumeration classes and why they are useful when you need to represent distinct values or states more expressively and safely than using constants or plain integers. An enumeration is a group of symbolic names tied to constant values called enumeration members. This blog post will discuss how to use the Enum module in Python, which was introduced in Python 3.4.
