Pandas Series.to_list()

Pandas Series.to_list() Tutorial

In this tutorial, we'll explore the Series.to_list() method in Pandas, which is used to convert a Pandas Series into a Python list, with well detailed example programs.

Syntax

The syntax of Series.to_list() is straightforward, with no additional parameters:

Series.to_list()

The method returns a Python list containing the values of the Pandas Series.

This method is similar to Series.tolist().

Examples for Series.to_list()

1. Convert Series to Python List

In this example, we'll use Series.to_list() to convert a Pandas Series into a Python list.

Python Program

import pandas as pd

# Create a Series
series = pd.Series({'Name': 'Alice', 'Age': 25, 'City': 'New York'})

# Convert the Series to a Python list
python_list = series.to_list()

# Print the original Series and the resulting Python list
print("Original Series:")
print(series)
print("\nResulting Python List:")
print(python_list)

Output

Original Series:
Name       Alice
Age           25
City    New York
dtype: object

Resulting Python List:
['Alice', 25, 'New York']

2. Convert Numeric Series to Python List

In this example, we'll use Series.to_list() to convert a numeric Pandas Series into a Python list.

Python Program

import pandas as pd

# Create a numeric Series
numeric_series = pd.Series([10, 20, 30, 40, 50])

# Convert the numeric Series to a Python list
numeric_list = numeric_series.to_list()

# Print the original Series and the resulting Python list
print("Original Numeric Series:")
print(numeric_series)
print("\nResulting Python List:")
print(numeric_list)

Output

Original Numeric Series:
0    10
1    20
2    30
3    40
4    50
dtype: int64

Resulting Python List:
[10, 20, 30, 40, 50]

Summary

In this tutorial, we've covered the Series.to_list() method in Pandas, which allows you to easily convert a Pandas Series into a Python list. This can be useful when you need to work with the data in list format or pass it to functions that expect a list.
