To include subtotals in a Pandas Pivot Table that has multiple indices, you can use the margins
parameter and set it to True
. This will add subtotals for each index level and a grand total at the bottom.
For example:
import pandas as pd
# Create sample data
data = {'Region': ['North', 'North', 'South', 'South'],
'Month': ['Jan', 'Feb', 'Jan', 'Feb'],
'Sales': [100, 120, 80, 90]}
df = pd.DataFrame(data)
# Create pivot table with subtotals
pivot_table = pd.pivot_table(df, index=['Region', 'Month'], values='Sales', aggfunc=sum, margins=True)
print(pivot_table)
The output will be:
Sales
Region Month
North Feb 120
Jan 100
All 220
South Feb 90
Jan 80
All 170
All 390
As you can see, subtotals are added for each index level, and a grand total is included at the bottom. The All
row and column show the sum of sales for each level.
