xarray.Dataset.any

Contents

xarray.Dataset.any#

Dataset.any(dim=None, *, keep_attrs=None, **kwargs)[source]#

Reduce this Dataset’s data by applying any along some dimension(s).

Parameters:
  • dim (str, Iterable of Hashable, "..." or None, default: None) – Name of dimension[s] along which to apply any. For e.g. dim="x" or dim=["x", "y"]. If “…” or None, will reduce over all dimensions.

  • keep_attrs (bool or None, optional) – If True, attrs will be copied from the original object to the new one. If False, the new object will be returned without attributes.

  • **kwargs (Any) – Additional keyword arguments passed on to the appropriate array function for calculating any on this object’s data. These could include dask-specific kwargs like split_every.

Returns:

reduced (Dataset) – New Dataset with any applied to its data and the indicated dimension(s) removed
