===============================
Boto3 - The AWS SDK for Python

Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) for
Python, which allows Python developers to write software that makes use
of services like Amazon S3 and Amazon EC2. You can find the latest, most
up to date, documentation at our doc site_, including a list of
services that are supported.

Boto3 is maintained and published by Amazon Web Services_.

Boto (pronounced boh-toh) was named after the fresh water dolphin native to the Amazon river. The name was chosen by the author of the original Boto library, Mitch Garnaat, as a reference to the company.

Notices

On 2025-04-22, support for Python 3.8 ended for Boto3. This follows the
Python Software Foundation end of support <https://peps.python.org/pep-0569/#lifespan>__
for the runtime which occurred on 2024-10-07.

Getting Started

Assuming that you have a supported version of Python installed, you can first
set up your environment with:

.. code-block:: sh

$ python -m venv .venv
...
$ . .venv/bin/activate

Then, you can install boto3 from PyPI with:

.. code-block:: sh

$ python -m pip install boto3

or install from source with:

.. code-block:: sh

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

Using Boto3

After installing boto3

Next, set up credentials (in e.g. ``~/.aws/credentials``):

.. code-block:: ini

    [default]
    aws_access_key_id = YOUR_KEY
    aws_secret_access_key = YOUR_SECRET

Then, set up a default region (in e.g. ``~/.aws/config``):

.. code-block:: ini

   [default]
   region=us-east-1

Other credential configuration methods can be found `here <https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html>`__

Then, from a Python interpreter:

.. code-block:: python

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

Running Tests
~~~~~~~~~~~~~
You can run tests in all supported Python versions using ``tox``. By default,
it will run all of the unit and functional tests, but you can also specify your own
``pytest`` options. Note that this requires that you have all supported
versions of Python installed, otherwise you must pass ``-e`` or run the
``pytest`` command directly:

.. code-block:: sh

    $ tox
    $ tox -- unit/test_session.py
    $ tox -e py26,py33 -- integration/

You can also run individual tests with your default Python version:

.. code-block:: sh

    $ pytest tests/unit
