When you make the API calls you're going to get back a list python objects
which you need to iterate. I believe some APIs will let you ask for
specific fields only, but this is simple enough:

    keystone = client.Client(username=Username, password=Password,
tenant_name=Tenant,
        auth_url='http://%s:5000/v2.0' % (Ip))
    tenants = keystone.tenants.list()
    tenant_ids = []
    for tenant in tenants:
        tenant_ids.append(tenant.id)

Then you can process the tenant_ids list, of course once you done that
you've lost the context of the object (like the name of the tenant).

For stuff like this the docs are your best bet along with introspecting the
objects using the interactive python shell:
