Python type hinting discussion #16

Open stscieisenhamer opened 7 years ago

stscieisenhamer commented 7 years ago

Be great to have a discussion of the if/how/when/why of using the new Python type hinting. Even if its the short "nope".

I'd like to hear @eteq comments on this. I'm pretty all over the place with my typing usage and I haven't really integrated mypy or black into my process yet. At the end of the day mypy enforces the annotations(typing) you write in your scripts so that you're not crossing data types in the same var-containers. I violate this with common statements like:

datum: typing.Dict[str, typing.Any] = {'data': []}
datum: typing.List[str] = datum['data']

☝️ maybe valid for mypy, but I wouldn't know

People are adopting it but not all packages support it. Python still not going to enforce it natively. Still a little controversial.
