How to perform addition and subtraction in Pandas using Python
• 1 minHere is how to perform additions and subtraction in Pandas using Python
Sample dataframe
# Import the Pandas library
import pandas as pd
# We create our example dataframe
df = pd.DataFrame(index = [2018, 2019, 2020, 2021, 2022], data=
{"eu_sales" : [12334, 12344, 521323, 709123, 1024566],
"us_sales" : [10452, 24198, 345222, 629452, 925123]})Addition
On columns
You can either sum up individual columns or use the .sum() method.
# Summing up individual columns
print(df["eu_sales"] + df["us_sales"])# Summing up all columns
print(df.sum(axis=1))df["total_sales"] = df["eu_sales"] + df["us_sales"]On rows
# Summing up all rows
print(df.sum())Subtraction
# Subtracting individual columns
print(df["total_sales"] - df["us_sales"])Here you are, you know pretty much everything that you would need about addition and subtraction with Pandas using Python.
