Square of the column in pandas python

Getting the square of the column in pandas python can be done in two ways using power function. Let’s see how to

  •         Get the square of the column in pandas python

With examples

First let’s create a dataframe

import pandas as pd
import numpy as np

df1 = {
    'State':['Arizona AZ','Georgia GG','Newyork NY','Indiana IN','Florida FL'],
   'Score':[4,47,55,74,31]}

df1 = pd.DataFrame(df1,columns=['State','Score'])
print(df1)

df1 will be

Square of the column in pandas python 1

 

Square of the column in pandas– Method 1:

Simply square the column and store in other column as shown below


df1['Score_Square']=df1['Score']**2
print(df1)

So the resultant dataframe will be

Square of the column in pandas python 2

 

Square of the column in pandas – Method 2:

Square the column using power function and store it in other column as shown below


df1['Score_square']=np.power((df1['Score']),2)
print(df1)

So the resultant dataframe will be

Square of the column in pandas python 3
