How to save Pandas DataFrame as CSV file?

This recipe helps you save Pandas DataFrame as CSV file

Recipe Objective

After working on a dataset and doing all the preprocessing we need to save the preprocessed data into some format like in csv , excel or others.

This python source code does the following :
1. Creates data dictionary and converts it into dataframe
2. Saves it in CSV format

So this is the recipe on how we can save Pandas DataFrame as CSV file.

Step 1 - Import the library

import pandas as pd

We have only imported pandas which is needed.

Step 2 - Setting up the Data

We have created a dictionary of data and passed it in pd.DataFrame to make a dataframe with columns 'first_name', 'last_name', 'age', 'Comedy_Score' and 'Rating_Score'. raw_data = {'first_name': ['Sheldon', 'Raj', 'Leonard', 'Howard', 'Amy'], 'last_name': ['Copper', 'Koothrappali', 'Hofstadter', 'Wolowitz', 'Fowler'], 'age': [42, 38, 36, 41, 35], 'Comedy_Score': [9, 7, 8, 8, 5], 'Rating_Score': [25, 25, 49, 62, 70]} df = pd.DataFrame(raw_data, columns = ['first_name', 'last_name', 'age', 'Comedy_Score', 'Rating_Score']) print(df)

Step 3 - Saving the DataFrame

So now we have to save the dataset that we have created. We save it in many format, here we are doing it in csv and excel by using to_csv and to_excel function respectively. df.to_csv('raw_data.csv', index=False) df.to_excel('raw_data.xls', index=False) So the output comes as two saved file one in csv format and other in excel format.


  first_name     last_name  age  Comedy_Score  Rating_Score
0    Sheldon        Copper   42             9            25
1        Raj  Koothrappali   38             7            25
2    Leonard    Hofstadter   36             8            49
3     Howard      Wolowitz   41             8            62
4        Amy        Fowler   35             5            70
