python enum class example

In Python, the enum module provides a way to create enumerations, which are sets of named values representing distinct elements. Enumerations make your code more readable and maintainable by giving meaningful names to constants.
Let's go through a step-by-step tutorial on how to use the enum class in Python with examples.
First, you need to import the Enum class from the enum module.
To create an enumeration, define a class that inherits from Enum and use class attributes to represent the named values.
In this example, Color is an enumeration with three values: RED, GREEN, and BLUE. The assigned values (1, 2, 3) are optional and can be omitted. If omitted, each value will be assigned an integer starting from 1.
You can access the values of the enumeration using dot notation.
You can iterate over the enumeration values using a for loop.
This will output:
You can use equality and identity operators to compare enum values.
You can also use strings as values for enums.
If you don't want to explicitly assign values, you can use the auto() function.
Using the enum module in Python allows you to create named constant values, making your code more readable and reducing the chances of errors. Enumerations are particularly useful when you have a predefined set of values that should not change during the program's execution.
Experiment with enums in your Python projects, and enjoy the benefits of cleaner and more maintainable code!
