* pylint / pep8 doesn't parse comment-based annotations, and thus flags imports that are in use as "unused"
* numbers.Real / Union[float,int] do not work correctly; I basically can't figure a way to annotate a function that takes an int/float/decimal/etc.
(mypy doesn't think "int" is a valid "Real", and it doesn't think you can add two Union[float,int] objects.)
(mypy has nonetheless been very helpful, and overall I would recommend it.)
- slaymaker1907 9y agoYou don't need comment based annotations since there are real annotations since python 3.5
- deathanatos 9y agoWhile true, my codebase regrettably needs to run in Python 2.7.
- make3 9y agoI can't tell if you're neglecting the fact that most production Python is Python 2 on purpose or not
- yorwba 9y ago> I basically can't figure a way to annotate a function that takes an int/float/decimal/etc. It seems like you should be able to just annotate it with float? ... when an argument is annotated as having type float , an argument of type int is acceptable ... https://www.python.org/dev/peps/pep-0484/#the-numeric-tower https://www.python.org/dev/peps/pep-0484/#the-numeric-tower
- deathanatos 9y agoHmm. I wasn't aware of that; still, it seems to not work for Decimal objects.
