-    from .dataarray import DataArray
-    from .dataset import Dataset
+    from .dataarray import DataArray  # noqa: F811
+    from .dataset import Dataset  # noqa: F811


This is a workaround to a flake8 limitation https://gitlab.com/pycqa/flake8/issues/553

xarray/core/dataset.py

+        elif isinstance(dim, Mapping):
+            # We're later going to modify dim in place; don't tamper with
+            # the input
+            dim = OrderedDict(dim)


Fixed bug where dim was modified in place, tainting the input variable. Also, fixed crash if the input dim is a read-only mapping.

+        append: bool = False,
+        inplace: bool = None,
+        **indexes_kwargs: Union[Hashable, Sequence[Hashable]]
+    ) -> 'Dataset':


Worth noting the behaviour is inconsistent with DataArray and pandas, which return None when inplace=True. Changing it however would benefit nobody and would break stuff.

This looks great!

xarray/core/dataarray.py

+        indexes: Mapping[Hashable, Union[Hashable, Sequence[Hashable]]] = None,
+        append: bool = False,
+        inplace: bool = None,
+        **indexes_kwargs: Union[Hashable, Sequence[Hashable]]


I'm guessing this is fine because mypy passes - my original thought was whether this should be Optional[Mapping] given it was either None or a dict?

As of mypy 0.701, x: MyType = None and x: Optional[MyType] = None are the same.

from typing import Optional def f1(x: int = None) -> None: pass def f2(x: Optional[int] = None) -> None: pass def f3(x: int = 1) -> None: pass def f4(x: Optional[int] = 1) -> None: pass f1() f2() f3() f4() f1(1) f2(1) f3(1) f4(1) f1(None) f2(None) f3(None) f4(None)

mypy output:

test_mypy.py:27: error: Argument 1 to "f3" has incompatible type "None"; expected "int"

@max-sixty I did a generalised cleanup of all already existing cases; I find it's much more readable now

max-sixty · 2019-07-15T15:13:50Z

xarray/core/dataset.py

+        self,
+        dims_or_levels: Union[Hashable, Sequence[Hashable]],
+        drop: bool = False,
+        inplace: bool = None,


inplace should go away soon so shouldn't matter... but should this be Optional[bool] given the default is None?

Great! Agree re Optional, thanks for clearing up.
Good to go from my end

Thanks @crusaderky ! I think fine to merge given we've both reviewed
