# xarray.core.coordinates.DatasetCoordinates

### *class* xarray.core.coordinates.DatasetCoordinates(dataset)[[source]](https://github.com/pydata/xarray/blob/main/xarray/core/coordinates.py#L884-L997)

Dictionary like container for Dataset coordinates (variables + indexes).

This collection can be passed directly to the [`Dataset`](xarray.Dataset.html.md#xarray.Dataset)
and [`DataArray`](xarray.DataArray.html.md#xarray.DataArray) constructors via their coords argument.
This will add both the coordinates variables and their index.
