How to Export Pandas DataFrame to the CSV File

Export Pandas DataFrame to the CSV File

In this tutorial, you are going to learn how to Export Pandas DataFrame to the CSV File in Python programming language. Here in this tutorial, we will do the following things to understand exporting pandas DataFrame to CSV file:

  1. Create a new DataFrame.
  2. Export the DataFrame to CSV File.

Basic Structure

df.to_csv(r’PATH_TO_STORE_EXPORTED_CSV_FILE\FILE_NAME.csv’)

1. Create new DataFrame

We are going to export the following data to CSV File:

Name Age Score
John 20 89
Sara 21 78
Jack 21 94
Ricky 20 56

Now let’s write the Python program for that:

First, we will import the pandas module and then we will create DataFrame.

NOTE: If you have not installed pandas package install it by using pip tutorial.

The following program simply creates a DataFrame and prints values:

# import pandas library first
from pandas import DataFrame
# import students DataFrame 
Students = {'Name': ['John','Sara','Jack','Ricky'],
        'Age': [20,21,21,20],
        'Score': [89,78,94,56]
       }
df = DataFrame(Students, columns= ['Name', 'Age', 'Score'])
print (df)

The output should be:

2. Export the DataFrame to CSV File

As given in the above program we have successfully created a DataFrame. Now to export the DataFrame to CSV file we are going to use the following function:

export_csv = df.to_csv(r’C:\Users\CrazyGeeks\Desktop\dataframe.csv’, index = None, header=True)

Where,

So the complete program should look like:

# Import pandas library first
from pandas import DataFrame
# Import students DataFrame 
Students = {'Name': ['John','Sara','Jack','Ricky'],
            'Age': [20,21,21,20],
            'Score': [89,78,94,56]
           }
# Create DataFrame
df = DataFrame(Students, columns= ['Name', 'Age', 'Score'])
# Export DataFrame to CSV File
export_csv = df.to_csv (r'C:\Users\CrazyGeeks\Desktop\dataframe.csv', index = None, header=True)
print (df)

The output file exported to desktop (C:\Users\CrazyGeeks\Desktop\dataframe.csv):

3. Another Example

If you don’t want to specify the specific location then you can just enter the name of the file. The exported file will be stored in the current directory where the program is located.

# Import pandas library first
from pandas import DataFrame
# Import students DataFrame 
Students = {'Name': ['John','Sara','Jack','Ricky'],
            'Age': [20,21,21,20],
            'Score': [89,78,94,56]
           }
# Create DataFrame
df = DataFrame(Students, columns= ['Name', 'Age', 'Score'])
# Export DataFrame to CSV File without specific location
export_csv = df.to_csv ('dataframe.csv', index = None, header=True)
print (df)
