Read CSV File without Unnamed Index Column in Python (Example)


In this article you’ll learn how to load a CSV file without an unnamed index column in Python programming.

The article consists of these contents:

It’s time to dive into the example:


Exemplifying Data & Software Libraries

We first need to load the pandas library to Python:

import pandas as pd                           # Import pandas library in Python

The following data is used as a basis for this Python programming tutorial:

data = pd.DataFrame({'x1':range(105, 113),    # Create pandas DataFrame
                     'x2':['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'],
                     'x3':[9, 2, 7, 3, 3, 1, 1, 8],
                     'x4':range(26, 18, - 1)})

Let’s export our data to create an exemplifying CSV file in our working directory

data.to_csv('data.csv')                       # Export pandas DataFrame

After running the previous Python code, you will find a new CSV file on your computer. We will use this CSV file for the following example.


Example: Import CSV File without Unnamed Index Column

The following Python code explains how to read a CSV file as a pandas DataFrame. In this DataFrame, the unnamed index column of the CSV file should be ignored.

For this task, we have to specify the index_col argument of the read.csv function to [0] as shown in the following Python syntax:

data_import = pd.read_csv('data.csv',         # Read pandas DataFrame from CSV
                          index_col = [0])
print(data_import)                            # Print imported pandas DataFrame


table 1 DataFrame read csv file without unnamed index column python


Have a look at the table that got returned by the previous Python syntax. It shows that our imported data comprises eight rows and four columns. You can also see that we have created a pandas DataFrame without showing an unnamed index column.
