Python 2 Enum Example

Certainly! It's important to note that Python 2 is no longer supported as of January 1, 2020. The Enum module was introduced in Python 3.4, so it's not available in Python 2. However, if you are using Python 3, you can use the Enum module for enumerations. Here's a tutorial with code examples:
The enum module in Python provides a way to create enumerations, which are a set of symbolic names (members) bound to unique, constant values. Enumerations are iterable, and their values can be compared.
To use enumerations in Python, you need to import the Enum class from the enum module:
You can define your enumeration by creating a class that inherits from Enum. Each member of the enumeration is an instance of the class:
In this example, Color is an enumeration with three members: RED, GREEN, and BLUE, each assigned a unique value.
You can access the members of an enumeration using dot notation:
Enumerations are iterable, allowing you to loop through their members:
This will output:
You can compare enumeration members using equality and identity operators:
You can access the values of enumeration members:
Enumerations can be used as values for function arguments to improve code readability and avoid magic numbers:
If you don't need to explicitly set values for members, Python can auto-assign them:
In this case, each member will be assigned a unique value automatically.
The Enum module in Python provides a clean and readable way to define enumerations, making your code more expressive and less error-prone. If you are using Python 3, it's recommended to leverage the enum module for such scenarios.
