Description
Consider the following perfectly valid python code:
from enum import IntEnum, Enum
class Colors(IntEnum):
RED = 0
BLUE = 1
class Colors2(int, Enum): # E: Definition of "__new__" in base class "int" is incompatible with definition in base class "Enum"
GREEN = 0
PURPLE = 1
for color in Colors: # E: Type[Colors] has no attribute "__iter__"
print(color.name)
for color in Colors2: # E: Type[Colors2] has no attribute "__iter__"
print(color.name)This probably has to do with support for metaclasses. Here is the output from mypy and python.
$ mypy e.py
e.py:7: error: Definition of "__new__" in base class "int" is incompatible with definition in base class "Enum"
e.py:11: error: Iterable expected
e.py:11: error: Type[Colors] has no attribute "__iter__"
e.py:14: error: Iterable expected
e.py:14: error: Type[Colors2] has no attribute "__iter__"
$ mypy e.py --py2
e.py:7: error: Definition of "__new__" in base class "int" is incompatible with definition in base class "Enum"
e.py:11: error: Iterable expected
e.py:11: error: Type[Colors] has no attribute "__iter__"
e.py:14: error: Iterable expected
e.py:14: error: Type[Colors2] has no attribute "__iter__"
$ python3 e.py
RED
BLUE
GREEN
PURPLE
$ python e.py
RED
BLUE
GREEN
PURPLE
