How to Convert Index to Column in Pandas Dataframe? Last Updated : 15 Jul, 2025 Comments Improve Suggest changes 3 Likes Like Report Pandas is a powerful tool which is used for data analysis and is built on top of the python library. The Pandas library enables users to create and manipulate dataframes (Tables of data) and time series effectively and efficiently. These dataframes can be used for training and testing machine learning models and Analyzing data. Converting Index to Columns By default, each row of the dataframe has an index value. The rows in the dataframe are assigned index values from 0 to the (number of rows - 1) in a sequentially order with each row having one index value. There are many ways to convert an index to a column in a pandas dataframe. Let's create a dataframe. Python3 # importing the pandas library as pd import pandas as pd # Creating the dataframe df df = pd.DataFrame({'Roll Number': ['20CSE29', '20CSE49', '20CSE36', '20CSE44'], 'Name': ['Amelia', 'Sam', 'Dean', 'Jessica'], 'Marks In Percentage': [97, 90, 70, 82], 'Grade': ['A', 'A', 'C', 'B'], 'Subject': ['Physics', 'Physics', 'Physics', 'Physics']}) # Printing the dataframe df Output: Method 1: The simplest method is to create a new column and pass the indexes of each row into that column by using the Dataframe.index function. Python3 import pandas as pd df = pd.DataFrame({'Roll Number': ['20CSE29', '20CSE49', '20CSE36', '20CSE44'], 'Name': ['Amelia', 'Sam', 'Dean', 'Jessica'], 'Marks In Percentage': [97, 90, 70, 82], 'Grade': ['A', 'A', 'C', 'B'], 'Subject': ['Physics', 'Physics', 'Physics', 'Physics']}) # Printing the dataframe df['index'] = df.index df Output: Method 2: We can also use the Dataframe.reset_index function to convert the index as a column. The inplace parameter reflects the change in the dataframe to stay permanent. Python3 import pandas as pd df = pd.DataFrame({'Roll Number': ['20CSE29', '20CSE49', '20CSE36', '20CSE44'], 'Name': ['Amelia', 'Sam', 'Dean', 'Jessica'], 'Marks In Percentage': [97, 90, 70, 82], 'Grade': ['A', 'A', 'C', 'B'], 'Subject': ['Physics', 'Physics', 'Physics', 'Physics']}) # Printing the dataframe df.reset_index(level=0, inplace=True) df Output: Create Quiz Comment H haniel Follow 3 Improve H haniel Follow 3 Improve Article Tags : Python Python-pandas Python pandas-dataFrame Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
