## Introduction

Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) for Python, allowing Python developers to write software that makes use of services like Amazon S3 and Amazon EC2. Maintained and published by Amazon Web Services, Boto3 is a critical tool for cloud management and integration.

The project has garnered significant attention, boasting 9868 stars and 1977 forks on GitHub, reflecting its widespread adoption and community engagement. It is licensed under Apache-2.0, promoting open use and collaboration.

**Important Notice:** Support for Python 3.9 for Boto3 ended on 2026-04-29. This follows the Python Software Foundation's end of support for the runtime, which occurred on 2025-10-31. For more details on deprecations, refer to the [AWS developer blog post](https://aws.amazon.com/blogs/developer/python-support-policy-updates-for-aws-sdks-and-tools/).

## Installation

Assuming you have a supported version of Python installed, you can first set up your environment and then install Boto3 from PyPI:

sh
python -m venv .venv
. .venv/bin/activate
python -m pip install boto3


Alternatively, you can install from source by cloning the repository and installing dependencies:

sh
git clone https://github.com/boto/boto3.git
cd boto3
python -m pip install -r requirements.txt
python -m pip install -e .


## Examples

After installing Boto3, you'll need to set up your AWS credentials (e.g., in `~/.aws/credentials`) and a default region (e.g., in `~/.aws/config`). More credential configuration methods can be found in the [official documentation](https://docs.aws.amazon.com/boto3/latest/guide/credentials.html).

Here's a simple example to list all S3 buckets associated with your AWS account from a Python interpreter:

python
import boto3

s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
    print(bucket.name)


## Why Use Boto3

Boto3 stands out as the official AWS SDK for Python, offering comprehensive access to virtually all AWS services. Its object-oriented API for services like S3 and EC2 simplifies complex cloud operations, making it easier to build robust and scalable applications. Developers can leverage Boto3 to automate AWS tasks, manage infrastructure, and seamlessly integrate Python applications with the vast AWS ecosystem.

With extensive and up-to-date documentation, along with a large and active community, developers can find ample resources and support for their projects. Boto3 is an indispensable library for anyone looking to interact with AWS programmatically using Python.
