Hi Guys,

Thanks for the inputs!

I used the same flow as the CLI part of the swift client, as John
suggested. I found it strange that the CLI and the python client APIs are
not unified, I imagined that I would have found the same interfaces after
some call layers.

So this is what I did:

import swiftclient.service
from swiftclient.service import SwiftService

swiftclient.service._default_global_options['os_username'] = ''
swiftclient.service._default_global_options['os_password'] = ''
swiftclient.service._default_global_options['os_tenant_name'] = ''
swiftclient.service._default_global_options['os_auth_url'] = ''

container_name = 'newcont'
filename = ['large_object']
segment_size = '1048576'

with SwiftService() as sw:
    for r in sw.upload(container_name, filename, {'segment_size':
segment_size}):
        print r['success']


The shade approach is actually the cleanest one!
