Boto, a Python interface, is offered by Amazon Web Services and all of its features work with Python 2.6 and 2.7. The next major version to support Python 3.3 is underway.

To get started with AWS SDK for Python (Boto), it is necessary to install the following on your development machine:

Proceed with the following steps to install the packages and run the sample application:

The sample code works as shown in the following diagram; initiating the credentials to allow access to Amazon S3, creating a bucket in a region, putting and getting objects into the bucket, and then finally deleting the objects and the bucket.

Now, let's run the sample application and see the output of the preceding command, as shown in the following screenshot, and then follow the source code step by step:

Now, let's examine the sample code; the path is aws-python-sample/s3-sample.py.

The connect_s3 method creates a connection for accessing S3:

s3 = boto.connect_s3()

The create_bucket method creates an S3 bucket with the specified name defined as the bucket_name variable in the standard US region by default:

bucket_name = "python-sdk-sample-%s" % uuid.uuid4()
print "Creating new bucket with name: " + bucket_name
bucket = s3.create_bucket(bucket_name)

By creating a new key object, it stores new data in the bucket:

from boto.s3.key import Key 
k = Key(bucket)
k.key = 'python_sample_key.txt'

The delete method deletes all the objects in the bucket:

k.delete()

The delete_bucket method deletes the bucket:

bucket.s3.delete_bucket(bucket_name)

The whole sample code is as follows:

import boto
import uuid
s3 = boto.connect_s3()
bucket_name = "python-sdk-sample-%s" % uuid.uuid4()
print "Creating new bucket with name: " + bucket_name
bucket = s3.create_bucket(bucket_name)
from boto.s3.key import Key
k = Key(bucket)
k.key = 'python_sample_key.txt'
print "Uploading some data to " + bucket_name + " with key: " + k.key
k.set_contents_from_string('Hello World!')
expires_in_seconds = 1800
print "Generating a public URL for the object we just uploaded. This URL will be active for %d seconds" % expires_in_seconds
print
print k.generate_url(expires_in_seconds)
print
raw_input("Press enter to delete both the object and the bucket...")
print "Deleting the object."
k.delete()
print "Deleting the bucket."
s3.delete_bucket(bucket_name)
