Adding new column to existing DataFrame in Pandas

Import pandas package

import pandas as pd

 

# Define a dictionary containing Students data

data = {‘Name’: [‘Jai’, ‘Princi’, ‘Gaurav’, ‘Anuj’],

‘Height’: [5.1, 6.2, 5.1, 5.2],

‘Qualification’: [‘Msc’, ‘MA’, ‘Msc’, ‘Msc’]}

 

# Convert the dictionary into DataFrame

df = pd.DataFrame(data)

 

# Declare a list that is to be converted into a column

address = [‘Delhi’, ‘Bangalore’, ‘Chennai’, ‘Patna’]

 

# Using ‘Address’ as the column name

# and equating it to the list

df[‘Address’] = address

 

# Observe the result

df
