Instead, any line that begins with `>>> ` will be assumed to be doctest lines. So with that, the numbers mean: line 201, character 27. When created that file we decided to skip the `generate_*` file, but because the file was renamed that rule does not work anymore.

Technically, that's a bug (the triple quotes mark the end of the docstring), but one that is a bit tricky to fix: `blackdoc` is implemented using a line parser, which does not work too well if the transition happen somewhere within the line. My guess is that it would have to start counting quotes which I've tried to avoid up until now since there's a lot of details to get right (see also keewis/blackdoc#145) Edit: for now, I guess it would be fine to add something like `The closing quotes are not on their own line.` to the error message","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1403614394 https://github.com/pydata/xarray/pull/7152#issuecomment-1287768499,https://api.github.com/repos/pydata/xarray/issues/7152,1287768499,IC_kwDOAMm_X85Mwcmz,14371165,2022-10-22T11:38:03Z,2022-10-22T11:38:03Z,MEMBER,"@dcherian cumsum for resample fails for some reason do you have any ideas? ```python import numpy as np import pandas as pd import xarray as xr da = xr.DataArray( np.array([1, 2, 3, 1, 2, np.nan]), dims=""time"", coords=dict( time=(""time"", pd.date_range(""01-01-2001"", freq=""M"", periods=6)), labels=(""time"", np.array([""a"", ""b"", ""c"", ""c"", ""b"", ""a""])), ), ) ds = xr.Dataset(dict(da=da)) a = ds.resample(time=""3M"") a.cumsum() Traceback (most recent call last): File ""C:\Users\J.W\anaconda3\envs\xarray-tests\lib\site-packages\spyder_kernels\py3compat.py"", line 356, in compat_exec exec(code, globals, locals) File ""c:\users\j.w\documents\github\xarray\xarray\util\untitled2.py"", line 20, in a.cumsum() File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\_aggregations.py"", line 4921, in cumsum return self.reduce( File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\resample.py"", line 395, in reduce return super().reduce( File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\groupby.py"", line 1357, in reduce return self.map(reduce_dataset) File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\resample.py"", line 342, in map return combined.rename({self._resample_dim: self._dim}) File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\dataset.py"", line 3646, in rename return self._rename(name_dict=name_dict, **names) File ""C:\Users\J.W\Documents\GitHub\xarray\xarray\core\dataset.py"", line 3587, in _rename raise ValueError( ValueError: cannot rename '__resample_dim__' because it is not a variable or dimension in this dataset ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1403614394 https://github.com/pydata/xarray/pull/7152#issuecomment-1287768091,https://api.github.com/repos/pydata/xarray/issues/7152,1287768091,IC_kwDOAMm_X85Mwcgb,14371165,2022-10-22T11:35:14Z,2022-10-22T11:35:14Z,MEMBER,"@keewis do you understand this blackdoc error? ``` trim trailing whitespace.................................................Passed fix end of files.........................................................Passed check yaml...............................................................Passed debug statements (python)................................................Passed mixed line ending........................................................Passed autoflake................................................................Passed isort....................................................................Passed pyupgrade................................................................Passed black....................................................................Passed black-jupyter............................................................Passed blackdoc.................................................................Failed - hook id: blackdoc - exit code: 123 error: cannot format /code/xarray/util/generate_aggregations.py: Cannot parse: 201:27: EOF in multi-line string Oh no! 💥 💔 💥 215 files left unchanged, 1 file fails to reformat. ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1403614394 https://github.com/pydata/xarray/pull/7152#issuecomment-1287253517,https://api.github.com/repos/pydata/xarray/issues/7152,1287253517,IC_kwDOAMm_X85Mue4N,2448579,2022-10-21T17:35:03Z,2022-10-21T17:35:03Z,MEMBER,"> o you think it would be better to finish this PR as the creation of _aggregations.py to give the cum methods better documentation?
