pandas.Panel.rename_axis

Panel.rename_axis(mapper, axis=0, copy=True, inplace=False)

Alter the name of the index or columns.

Parameters:

mapper : scalar, list-like, optional

Value to set as the axis name attribute.

axis : {0 or ‘index’, 1 or ‘columns’}, default 0

The index or the name of the axis.

copy : boolean, default True

Also copy underlying data.

inplace : boolean, default False

Modifies the object directly, instead of creating a new Series or DataFrame.

Returns:

renamed : Series, DataFrame, or None

The same type as the caller or None if inplace is True.

Notes

Prior to version 0.21.0, rename_axis could also be used to change the axis labels by passing a mapping or scalar. This behavior is deprecated and will be removed in a future version. Use rename instead.

Examples

Series

>>> s = pd.Series([1, 2, 3])
>>> s.rename_axis("foo")
foo
0    1
1    2
2    3
dtype: int64

DataFrame

>>> df = pd.DataFrame({"A": [1, 2, 3], "B": [4, 5, 6]})
>>> df.rename_axis("foo")
     A  B
foo
0    1  4
1    2  5
2    3  6

>>> df.rename_axis("bar", axis="columns")
bar  A  B
0    1  4
1    2  5
2    3  6
