df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.index = pd.RangeIndex(start=1, stop=len(df) + 1)
print(df)Output:
Name Score 1 Alice 85 2 Bob 92
With this approach, the DataFrame’s index is replaced with a new index created by pd.RangeIndex, starting from 1. This makes the DataFrame more readable and can be helpful when the original index is meaningless.
Method 4: Exporting to CSV Without Index
When you’re exporting a DataFrame to a CSV for sharing data, you can use the to_csv() method, ensuring the index=False parameter is set. This avoids writing the DataFrame’s index in the CSV file.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.to_csv('scores.csv', index=False)This code snippet creates a CSV file named ‘scores.csv’ with the DataFrame’s data, excluding the index column. The CSV file generated by this function will not include an index.
Bonus One-Liner Method 5: Formatting with format()
You can also display a DataFrame without an index directly within a Python script by combining the print() function with string formatting. This is a quick and easy one-liner approach.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
print(f"{df.to_string(index=False)}")In this example, the DataFrame is converted to a string without the index using to_string(index=False) and then formatted and printed.

hide_index()fromStyler. Best for Jupyter notebooks. Useful for inline DataFrame styling. Limited to Jupyter environments. - Method 3: Reassigning the Index. Offers a permanent solution by changing the index. Useful when the index itself needs to be meaningful. Requires carefully choosing a new index.

df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
print(df.style.hide_index())Output:
/* A table without index column will be shown in Jupyter Notebook */
This example demonstrates how to use the Styler object’s hide_index() method, which removes the index column from the displayed DataFrame in a Jupyter notebook.
Method 3: Reassigning the Index
If you wish to remove the index for further operations (not just for display), you can reassign the index to some other column or a range of numbers that might be more relevant to your data.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.index = pd.RangeIndex(start=1, stop=len(df) + 1)

If you wish to remove the index for further operations (not just for display), you can reassign the index to some other column or a range of numbers that might be more relevant to your data.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.index = pd.RangeIndex(start=1, stop=len(df) + 1)
print(df)Output:
Name Score 1 Alice 85 2 Bob 92
With this approach, the DataFrame’s index is replaced with a new index created by pd.RangeIndex, starting from 1. This makes the DataFrame more readable and can be helpful when the original index is meaningless.
Method 4: Exporting to CSV Without Index
When you’re exporting a DataFrame to a CSV for sharing data, you can use the to_csv() method, ensuring the index=False parameter is set. This avoids writing the DataFrame’s index in the CSV file.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.to_csv('scores.csv', index=False)This code snippet creates a CSV file named ‘scores.csv’ with the DataFrame’s data, excluding the index column. The CSV file generated by this function will not include an index.
Bonus One-Liner Method 5: Formatting with format()
You can also display a DataFrame without an index directly within a Python script by combining the print() function with string formatting. This is a quick and easy one-liner approach.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
print(f"{df.to_string(index=False)}")In this example, the DataFrame is converted to a string without the index using to_string(index=False) and then formatted and printed.
Summary/Discussion
- Method 1:
to_string()withindex=False. Simple and direct approach for text-based environments. Cannot be used for visual presentation in notebooks. - Method 2:
hide_index()fromStyler. Best for Jupyter notebooks. Useful for inline DataFrame styling. Limited to Jupyter environments. - Method 3: Reassigning the Index. Offers a permanent solution by changing the index. Useful when the index itself needs to be meaningful. Requires carefully choosing a new index.
- Method 4: Exporting to CSV Without Index. Ideal for data sharing and exporting. Does not affect DataFrame display within Python environment; only impacts the exported file.
- Method 5: Formatting with

💡 Problem Formulation: When working with pandas DataFrames in Python, the default display includes an index alongside the data columns. However, there are scenarios where the index may be irrelevant or aesthetically cumbersome, such as in data presentation or reports. For instance, if you have a DataFrame containing student scores, you might want to present this information without the distracting index column. This article outlines how to achieve a cleaner display by removing or hiding the index.
Method 1: Using to_string() with index=False
The to_string() method in pandas can be manipulated to exclude the index from the DataFrame’s string representation by setting the index parameter to False. This method is typically used for displaying DataFrames as a string, which is especially useful in text-based environments like terminals or text files.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
print(f"{df.to_string(index=False)}")In this example, the DataFrame is converted to a string without the index using to_string(index=False) and then formatted and printed.

When you’re exporting a DataFrame to a CSV for sharing data, you can use the to_csv() method, ensuring the index=False parameter is set. This avoids writing the DataFrame’s index in the CSV file.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
df.to_csv('scores.csv', index=False)This code snippet creates a CSV file named ‘scores.csv’ with the DataFrame’s data, excluding the index column. The CSV file generated by this function will not include an index.
Bonus One-Liner Method 5: Formatting with format()
You can also display a DataFrame without an index directly within a Python script by combining the print() function with string formatting. This is a quick and easy one-liner approach.
Here’s an example:
df = pd.DataFrame({'Name': ['Alice', 'Bob'], 'Score': [85, 92]})
print(f"{df.to_string(index=False)}")In this example, the DataFrame is converted to a string without the index using to_string(index=False) and then formatted and printed.
Summary/Discussion
- Method 1:
to_string()withindex=False. Simple and direct approach for text-based environments. Cannot be used for visual presentation in notebooks. - Method 2:
hide_index()fromStyler. Best for Jupyter notebooks. Useful for inline DataFrame styling. Limited to Jupyter environments. - Method 3: Reassigning the Index. Offers a permanent solution by changing the index. Useful when the index itself needs to be meaningful. Requires carefully choosing a new index.
- Method 4: Exporting to CSV Without Index. Ideal for data sharing and exporting. Does not affect DataFrame display within Python environment; only impacts the exported file.
- Method 5: Formatting with
format(). Quick and concise for scripting. Limits in customization and only suitable for small-scale display needs.
