python enum vs intenum
Показать описание
Enums, or enumerations, are a powerful feature in Python that allow you to create named constant values. They provide a way to represent a set of unique named values in a more readable and maintainable manner. In this tutorial, we'll explore two types of enums in Python: Enum and IntEnum, and understand the key differences between them.
The Enum class in Python is part of the enum module and allows you to create enumerations with arbitrary values. These values can be of any type, and they don't have to be integers. Let's create a simple example using Enum:
In the above example, we've defined an enumeration called Color with three members: RED, GREEN, and BLUE. Each member has an associated value, which can be any type.
The IntEnum class, also part of the enum module, is a subclass of Enum that restricts the values to integers. This is useful when you want to enforce that the values of your enumeration are only integers. Let's create a similar example using IntEnum:
In this example, we've defined an enumeration called Weekday with seven members representing the days of the week. Each member has an associated integer value.
Type Enforcement:
Comparison Behavior:
Use Cases:
Choosing between Enum and IntEnum depends on the specific requirements of your application. If you need the flexibility to use values of any type, Enum is the right choice. If you want to enforce that your enumeration values are integers, use IntEnum. Understanding these differences will help you make informed decisions when designing and implementing your enums in Python.
