As briefly mentioned above, we can iterate through enum members using for loops. This allows us to print out all of the members of the enum class. As you can see in the example below, we can also include keywords likenameandvaluein the for loop to display data in a more structured way...
enum in Python By: Rajesh P.S.In Python, you can implement an enumeration using the enum module, which provides a way to create named constant values that have a meaningful representation. Enumerations make your code more readable and maintainable by providing a clear and self-explanatory way ...

In Python 3.12 it will be possible to check for member values and not just members; until then, a TypeError will be raised if a non-Enum-member is used in a containment check. __dir__(cls) Returns ['__class__', '__doc__', '__members__', '__module__'] and the names of ...

Often, the members of an enumeration take consecutive integer values. However, in Python, the values of members can be of any type, including user-defined types. For example, here’s an enumeration of school grades that uses non-consecutive numeric values in descending order:...

关于python中Enum的个人总结 关于python中Enum的个人总结初识 可以通过enum模块导入 语法 初始化: 可以通过enum_ = Enum('class_name', names,start = 1)来创建,其中names可以是字符串,可以是列表/元组。内部定义为: def _create_(cls, class_name, names, *, module=None, qualname=None, type=None, ...
