我有一个
    myenum(str, Enum):
       COLORRED = 'colorred'
       COLORBLUE = 'colorblue'
    itemList = [<myenum.COLORRED,'colorred'>]
我试图从itemList中获取'coloured'的值，但`itemList.value`在Python中会引发类型检查错误，错误消息为"str has no attribute value"。
list(map(str, myenum))会返回键COLORRED，但我需要值'coloured'。我尝试了https://stackoverflow.com/questions/58608361/string-based-enum-in-python，但都对我不起作用。
我的枚举是由openapi自动生成的。以下是它的yaml。
我收到myElements数组，并需要myEnum中的一个值。
    myElements:
      type: array
      items:
      allOf:
         - $ref: 'myEnum'
    
    myEnum:
      type: String
      enum:
        - 'state1'
        - 'state2'
注意：问题出在Python的类型检查上，而不是在迭代值上。我需要在不使用`.values`或`.name`的情况下获取枚举值。

I have a 
    myenum(str, Enum):
       COLORRED = &#39;colorred&#39;
       COLORBLUE = &#39;colorblue&#39;
    itemList = [&lt;myenum.COLORRED,&#39;colorred&#39;&gt;]
I am trying to get value from itemList &#39;coloured&#39; but `itemList.value` gives a type check error in Python with the error message &quot;str has no attribute value&quot;. 
  
list(map(str,myenum)) gives key COLORRED but I need the value &#39;coloured&#39;. I tried https://stackoverflow.com/questions/58608361/string-based-enum-in-python but none of them are working for me.
My enum is auto generated by openapi. below is yaml for it.
I receive array of myElements and need one value in myEnum.
    myElements:
      type: array
      items:
      allOf:
         - $ref: &#39;myEnum&#39;
    
    myEnum:
      type: String
      enum:
        - &#39;state1&#39;
        - &#39;state2&#39;
Note: Issue is with typecheck in python not iterating the values. I need enum values without using .values or .name

看起来你试图使用列表的`.value`属性，而不是它的元素。
```python
from enum import Enum
class Color(Enum):
    RED = "color red"
    BLUE = "color blue"
lst = [Color.RED, Color.BLUE]
expected = ['color red', 'color blue']
# 这等同于 `list(map(lambda v: v.value, lst))`
values = [item.value for item in lst]
assert values == expected

class Color(StrEnum):
    RED = 'red'
    GREEN = 'green'
    BLUE = 'blue'
print(Color.RED)  # => red

from enum import Enum
class myenum(str, Enum):
    COLORRED = 'colorred'
    COLORBLUE = 'colorblue'
mylist = [x.value for x in myenum]
# where mylist will be ['colorred', 'colorblue']
