所以第10行,type(Shape.CIRCLE)的结果是<enum 'Shape'>。 # enum.py89.class_EnumDict(dict):"""Track enum member order and ensure member names are not reused.EnumMeta will use the names found in self._member_names as theenumeration member names."""...90.def__setitem__(self,key,value):...

3. 虽然使用class关键字创建,但枚举并不是常规意义上的python类 枚举成员的展现形式: 代码语言:javascript 复制 >>>print(Color.RED)Color.RED>>>print(repr(Color.RED))<Color.RED:2> 枚举成员的type类型是其所属的枚举类: 代码语言:javascript 复制 >>>type(Color.RED)<enum'Color'>>>isinstance(Color.RE...
Python枚举类型Enum用法 枚举类型可以看作是一种标签或是一系列常量的集合,通常用于表示某些特定的有限集合。 代码语言:javascript 复制 fromenumimportEnumclassColor(Enum):RED=1GREEN=2BLOCK=3print(Color.RED)print(Color.RED.value)print(Color.RED.name) 结果: 上面的代码创建了一个基本的枚举示例,与我们普通类...
