Boto3 - The AWS SDK for Python

Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) forPython, which allows Python developers to write software that makes useof services like Amazon S3 and Amazon EC2. You can find the latest, mostup to date, documentation at our doc site, including a list ofservices that are supported.

On 01/15/2021 deprecation for Python 2.7 was announced and support was droppedon 07/15/2021. To avoid disruption, customers using Boto3 on Python 2.7 mayneed to upgrade their version of Python or pin the version of Boto3. Formore information, see this blog post.

Getting Started

Assuming that you have Python and virtualenv installed, set up your environment and install the required dependencies like this or you can install the library using pip:

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

$ python -m pip install boto3

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 credentials configuration method 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 ownpytest options. Note that this requires that you have all supportedversions of Python installed, otherwise you must pass -e or run thepytest 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
