How to get total of Pandas column?

Given a Pandas DataFrame, we have to get the total of columns.

Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of DataFrame. DataFrames are 2-dimensional data structures in pandas. DataFrames consist of rows, columns, and the data. The Data inside the DataFrame can be of any type.

Pandas allows us to get the total sum of a column, but the column values should be a number. However a particular column may consist of similar values, so if we want to get the sum of unique values we can group by the values of that column and use the sum() method or if we want the sum of all the values then we can directly use the sum() method.

To work with pandas, we need to import pandas package first, below is the syntax:

import pandas as pd

Let us understand with the help of an example,

# Importing pandas package
import pandas as pd

# Importing numpy package
import numpy as np

# Creating a dictionary
d = {
    'A':[35,54,44,45,33,22],
    'B':[928,28,23,2343,232,22],
    'C':[221,24,22,20,332,22]
}

# Creating a DataFrame
df = pd.DataFrame(d)

# Display DataFrame
print("Created DataFrame:\n",df,"\n")

Output:

Suppose we want to get the sum of the column 'B', we ill use the following code:

# Get the sum of column B
Total = df['B'].sum()

# Display total
print("Total sum:\n",Total)

Output:
