pandas.DataFrame.__dataframe__

DataFrame.__dataframe__(nan_as_null=False, allow_copy=True)[source]

Return the dataframe interchange object implementing the interchange protocol.

Parameters

nan_as_null:bool, default False

Whether to tell the DataFrame to overwrite null values in the data with NaN (or NaT).

allow_copy:bool, default True

Whether to allow memory copying when exporting. If set to False it would cause non-zero-copy exports to fail.

Returns

DataFrame interchange object

The object which consuming library can use to ingress the dataframe.

Notes

Details on the interchange protocol: https://data-apis.org/dataframe-protocol/latest/index.html

nan_as_null currently has no effect; once support for nullable extension dtypes is added, this value should be propagated to columns.
