Python | Pandas Panel.add()
  • Last Updated : 28 Jan, 2019

In Pandas, Panel is a very important container for three-dimensional data. The names for the 3 axes are intended to give some semantic meaning to describing operations involving panel data and, in particular, econometric analysis of panel data.

In Pandas Panel.add() function is used for element-wise addition of series and series/dataframe.

Syntax: Panel.add(other, axis=0)

Parameters:
other : DataFrame or Panel
axis : Axis to broadcast over

Returns: Panel
