pandas.Panel.rename

Panel.rename(items=None, major_axis=None, minor_axis=None, **kwargs)

Alter axes input function or functions. Function / dict values must be unique (1-to-1). Labels not contained in a dict / Series will be left as-is. Alternatively, change Series.name with a scalar value (Series only).

Parameters:

items, major_axis, minor_axis : scalar, list-like, dict-like or function, optional

Scalar or list-like will alter the Series.name attribute, and raise on DataFrame or Panel. dict-like or functions are transformations to apply to that axis’ values

copy : boolean, default True

Also copy underlying data

inplace : boolean, default False

Whether to return a new Panel. If True then value of copy is ignored.

Returns:

renamed : Panel (new object)
