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.rsub() function is used to get the subtraction of series and dataframe/Panel.
Syntax: Panel.rsub(other, axis=0)
Parameters:
other : DataFrame or Panel
axis : Axis to broadcast overReturns: Panel
Code #1:
# importing pandas module import pandas as pd import numpy as np   df1 = pd.DataFrame({'a': ['Geeks', 'For', 'neveropen', 'real'],                     'b': [111, 123, 425, 1333]})   df2 = pd.DataFrame({'a': ['I', 'am', 'dataframe', 'two'],                     'b': [100, 100, 100, 100]})                       data = {'item1':df1, 'item2':df2}   # creating Panel panel = pd.Panel.from_dict(data, orient ='minor') print("panel['b'] is - \n\n", panel['b'])   print("\nSubtracting panel['b'] with df2['b'] using rsub() method - \n") print("\n", panel['b'].rsub(df2['b'], axis = 0)) |
Output:
panel['b'] is -
item1 item2
0 111 100
1 123 100
2 425 100
3 1333 100
