Boto3ΒΆ

In this page you will find documentation about the boto3 library, the AWS SDK for python. You can use it to access swift using the S3 API.

You can install the boto3 library by:

pip install boto3

Information on the S3 part of this library is at: http://boto3.readthedocs.io/en/latest/reference/services/s3.html

Below you find a piece of example code to:

  • list buckets
  • create a bucket
  • upload an object
  • adapt object metadata
  • get metadata
  • list the objects in a bucket
  • download an object
  • delete an object
  • delete a bucket
