# xarray.IndexVariable.any

#### IndexVariable.any(dim=None, \*\*kwargs)[[source]](https://github.com/pydata/xarray/blob/main/xarray/namedarray/_aggregations.py#L134-L186)

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

* **Parameters:**
  * **dim** ([`str`](https://docs.python.org/3/builtins/stdtypes.html#str), `Iterable` of `Hashable`, `"..."` or [`None`](https://docs.python.org/3/builtins/constants.html#None), *default*: [`None`](https://docs.python.org/3/builtins/constants.html#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.
  * **\*\*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** (`NamedArray`) – New NamedArray with `any` applied to its data and the
  indicated dimension(s) removed
