# xarray.Dataset.identical

#### Dataset.identical(other)[[source]](https://github.com/pydata/xarray/blob/main/xarray/core/dataset.py#L1803-L1878)

Check whether two Datasets are identical.

Like equals, but also checks all dataset attributes, the
attributes on all variables and coordinates, and indexes.
