List S3 object versions with Boto and Python

"""
List all S3 object versions

import os
from boto.s3.connection import S3Connection

print '--- Connecting to S3'
c = S3Connection(aws_access_key_id=os.environ['AWS_ACCESS_KEY_ID'],
        aws_secret_access_key=os.environ['AWS_SECRET_ACCESS_KEY'])

print '--- Selecting the bucket'
bucket = c.get_bucket('...')

versions = bucket.list()
#versions = bucket.list(prefix='')

print '--- List all bucket key versions'
for version in versions:
    print version

You can get a specific directory's contents by passing its name to the prefix attribute.

Just a note, I am not sure if the code above lists the versions of s3 objects, but instead just lists the keys. The following code might work better:

import boto
conn = boto.connect_s3()
bucket = conn.get_bucket('my-bucket')

# List version of objects filtered by the key foo/bar
versions = bucket.list_versions(prefix='foo/bar')
for version in versions:
    print version

All of these codes are printing the keys not the versions...
