DataFrame.set_axis(labels: IndexLabel, *, axis: Axis = 0, copy: bool | NoDefault = _NoDefault.no_default)[source]¶

Assign desired index to given axis.

Parameters:

• labels (list-like, Index, MultiIndex) – The values for the new index.

• axis ({index (0), rows(0), columns (1)}) – Axis for the function to be applied on.

• copy (bool, default True) – To maintain compatibility with pandas, does nothing.

Return type:
