Theenummodule is used for creating enumerations in Python. Enumerations are created with theclasskeyword or with the functional API. There are specific derived enumerationsenum.IntEnum,enum.IntFlag, andenum.Flag. Simple example The following is a simple example of a Python enumeration. main.py #...
Enum(value='NewEnumName', names=<...>, *, module='...', qualname='...', type=<mixed-in class>, start=1) 方式二:自定义枚举类。自定义枚举类必须继承自一个枚举基类,至多一个具体的数据类型以及0至多个混合类,自定义的枚举类不能实例化。
在Python中没有内置的枚举方法,起初模仿实现枚举属性的方式是 class Directions: NORTH = 1 EAST = 2 SOUTH = 3 WEST = 4 1. 2. 3. 4. 5. 使用成员 Direction.EAST Direction.SOUTH 1. 2. 检查成员 >>> print("North的类型:", type(Direction.NORTH)) ...
