Enum in Python is used foriteration and comparisonof the names (members) you assign to the class. We can use afor looptoiterate over all of the members of the enum class. But be aware that while we use the classsyntaxfor enums,enums are not treated as typical Python classes. How to...
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 ...

Python enum.IntEnum用法及代码示例 借助enum.IntEnum()方法,我们可以基于整数值获取枚举,如果与基于普通枚举的类进行比较,则使用enum.IntEnum()方法。 用法:enum.IntEnum 返回:IntEnum没有书面类型。 范例1: 在这个例子中,我们可以通过使用enum.IntEnum()方法,我们可以使用此方法基于整数值获取枚举。
Python >>> from enum import Enum >>> names = [] >>> while True: ... name = input("Member name: ") ... if name in {"q", "Q"}: ... break ... names.append(name.upper()) ... Member name: YES Member name: NO Member name: q >>> DynamicEnum = Enum("DynamicEnum...
通过这种方式,你可以轻松地获取Python枚举中的所有值。
Coming from Java or C where Enums are a way of life, it is hard to leave those habits behind and program Pythonically. But, not everything in the world of static compilation makes sense in the python world. These Enum() objects are slower than constants assigned to a variable name or...
