Python | Pandas Panel.add()

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

Code #1:

# importing pandas module
import pandas as pd
import numpy as np

df1 = pd.DataFrame({'a': ['Geeks', 'For', 'geeks', 'for', 'real'],
                    'b': [11, 1.025, 333, 114.48, 1333]})

data = {'item1':df1, 'item2':df1}

# creating Panel
panel = pd.Panel.from_dict(data, orient ='minor')

print("panel['b'] is - \n\n", panel['b'], '\n')

print("\nAdding panel['b'] with df1['b'] using add() method - \n")
print("\n", panel['b'].add(df1['b'], axis = 0))

Output:

Code #2:

# Create a 5 * 5 dataframe
df2 = pd.DataFrame(np.random.rand(5, 2), columns =['item1', 'item2'])
print("Newly create dataframe with random values is - \n\n", df2)

print("\nAdding panel['b'] with df2  using add() method - \n")
print(panel['b'].add(df2, axis = 0))

Output:
