折腾：
【已解决】Python的Flask中自定义的枚举对象序列化为JSON时出错：TypeError is not JSON serializable
期间，想要去寻找，Python中是否有已经预定义好的，已实现的，类似于IntEnum的String的Enum
其中已经知道了：
Enum是Python 3.4之后才有的
此处的Python 2.12中，已通过导入enum34，得以使用上了enum.Enum了。
StringEnum
python enum string enum
python enum IntEnum
8.13. enum — Support for enumerations — Python 3.5.2 documentation
python enum StrEnum
enum34-custom 0.7.2 : Python Package Index
那就去试试这个：
结果找不到：

算了。不去找了。
