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 2026-04-29, support for Python 3.9 will end for Boto3. This follows the Python Software Foundation `end of support `__ for the runtime which occurred on 2025-10-31. On 2025-04-22, support for Python 3.8 ended for Boto3. This follows the Python Software Foundation `end of support `__ for the runtime which occurred on 2024-10-07.

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 `__ 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 Getting Help ------------ We use GitHub issues for tracking bugs and feature requests and have limited bandwidth to address them. Please use these community resources for getting help: * Ask a question on `Stack Overflow `__ and tag it with `boto3 `__ * Open a support ticket with `AWS Support `__ * If it turns out that you may have found a bug, please `open an issue `__ Contributing ------------ We value feedback and contributions from our community. Whether it's a bug report, new feature, correction, or additional documentation, we welcome your issues and pull requests. Please read through this `CONTRIBUTING `__ document before submitting any issues or pull requests to ensure we have all the necessary information to effectively respond to your contribution. Maintenance and Support for SDK Major Versions ---------------------------------------------- Boto3 was made generally available on 06/22/2015 and is currently in the full support phase of the availability life cycle.
