New submission from Benyamin Guedj <[email protected]>:
when trying to implement mixing with enum
```python
from typing import Tuple
from enum import Enum
class Blah(Tuple[str, ...], Enum):
val = ('a', 'b')
```
>>> from typing import Tuple
>>> from enum import Enum
>>> class Blah(Tuple[str, ...], Enum):
... val = ('a', 'b')
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\enum.py", line
150, in __prepare__
member_type, first_enum = metacls._get_mixins_(cls, bases)
File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\enum.py", line
574, in _get_mixins_
member_type = _find_data_type(bases) or object
File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\enum.py", line
562, in _find_data_type
raise TypeError('%r: too many data types: %r' % (class_name, data_types))
TypeError: 'Blah': too many data types: [<class 'tuple'>, <class
'typing.Generic'>]
note:
the same code work on python 3.7, 3.9, 3.10
I have checked the source code of enum of 3.8
https://github.com/python/cpython/blob/3.8/Lib/enum.py
and it's not the same as the other version
https://github.com/python/cpython/blob/3.9/Lib/enum.py
