xarray.Index.create_variables

Index.create_variables(variables=None)

Maybe create new coordinate variables from this index.

This method is useful if the index data can be reused as coordinate variable data. It is often the case when the underlying index structure has an array-like interface, like pandas.Index objects.

The variables given as argument (if any) are either returned as-is (default behavior) or can be used to copy their metadata (attributes and encoding) into the new returned coordinate variables.

Note: the input variables may or may not have been filtered for this index.

Parameters:

variables (dict-like, optional) – Mapping of Variable objects.

Returns:

index_variables (dict-like) – Dictionary of Variable or IndexVariable objects.
