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 2023-12-13, support for Python 3.7 ended for Boto3. This follows the Python Software Foundation end of support for the runtime which occurred on 2023-06-27. For more information, see this blog post.

Getting Started

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

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

Then, you can install boto3 from PyPI with:

$ python -m pip install boto3

or install from source with:

$ 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):

[default]
aws_access_key_id = YOUR_KEY
aws_secret_access_key = YOUR_SECRET

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

[default]
region=us-east-1

Other credential configuration methods can be found here

Then, from a Python interpreter:

>>> 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:

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

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

$ pytest tests/unit
