1368900431,PR_kwDOAMm_X84-u2Jv,7020,Typing of abstract base classes,43316012,open,0,,,6,2022-09-11T10:27:01Z,2023-01-19T10:48:20Z,,COLLABORATOR,,0,pydata/xarray/pulls/7020,"This PR adds some typing to several abstract base classes that are used in xarray.

Most of it is working, only one major point I could not figure out:

What is the type of `NDArrayMixin.array`???
I would appreciate it if someone that has more insight into this would help me.

Several minor open points:

- What is the return value of `ExplicitlyIndexed.__getitem__`
- What is the return value of `ExplicitlyIndexed.transpose`
- What is the return value of `AbstractArray.data`
- `Variable.values` seems to be able to return scalar values which is incompatible with the `AbstractArray` definition.

Overall it seems that typing has helped to find some problems again :)

Mypy should fail for tests, I did not adopt them yet, want to solve the outstanding issues first.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7020/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

Currently every function that accepts multiple dimensions does this by itself.

I decided to first see if it would be useful to centralize the dimension parsing and collect inputs before adding it to other functions.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7051/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
