Function coerce_pandas_values

xarray/structure/merge.py:511–543

Convert pandas values found in a list of labeled objects. Parameters ---------- objects : list of Dataset or mapping The mappings may contain any sort of objects coercible to xarray.Variables as keys, including pandas objects. Returns ------- List of Dataset

(objects: Iterable[CoercibleMapping])
