In pandas I can do something like –

pd.read_csv(path).loc[lambda df: df.col > 10, cols]

And I’m wondering if there’s an equivalent in Xarray? I’ve tried –

xr.open_dataset(path)["var"].sel(
  time=lambda da: ~((da.time.dt.month == 2) & (da.time.dt.day == 29))
)

and

xr.open_dataset(path)["var"].loc[
  lambda da: ~((da.time.dt.month == 2) & (da.time.dt.day == 29))
]

Neither work. Obviously I can achieve this in two lines but it’s cleaner code to read when in one line given I have to open and process similarly multiple datasets.
