Create Empty pandas DataFrame in Python (2 Examples)

 

In this Python article you’ll learn how to initialize an empty DataFrame using the pandas library.

The tutorial contains the following content blocks:

Let’s do this…

 

Example 1: Create Empty pandas DataFrame without Column Names

Example 1 illustrates how to construct a pandas DataFrame with zero rows and zero columns.

As a first step, we have to load the pandas library to Python:

import pandas as pd                                  # Load pandas

Next, we can use the DataFrame() function to create an empty DataFrame object:

data_1 = pd.DataFrame()                              # Create empty DataFrame
print(data_1)                                        # Print empty DataFrame
# Empty DataFrame
# Columns: []
# Index: []

Have a look at the previous console output: We have created a pandas DataFrame with zero rows and no variables.

 

Example 2: Create Empty pandas DataFrame with Column Names

Example 2 explains how to initialize a pandas DataFrame with zero rows, but with predefined column names.

For this, we have to use the columns argument within the DataFrame() function as shown below:

data_2 = pd.DataFrame(columns = ["x1", "x2", "x3"])  # Create empty DataFrame with column names
print(data_2)                                        # Print empty DataFrame with column names
# Empty DataFrame
# Columns: [x1, x2, x3]
# Index: []

The previous output shows that we have created an empty data matrix with the three column names x1, x2, and x3.
