In my try, f-string formatting behavior of  str-based  Enum  members differs across Python versions

from enum import Enum
class MyEnum(str, Enum):
    IntOpt = "Integer?"

print(f"{MyEnum.IntOpt}")

In 3.10, it will be Integer? and in 3.11, 3.12, 3.13, it will be MyEnum.IntOpt
So I explicitly customize a __str__ function with {enum_name}.{member_name}
