AttributeError: 'BillingManagementClient' object has no attribute 'format_url'

[dpeanalyticswipro]

My Code:

from msrest import Serializer
from msrest import Deserializer
from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.billing import BillingManagementClient
from azure.mgmt.billing.billing_management_client import BillingManagementClientConfiguration
from azure.mgmt.billing.operations import BillingPeriodsOperations
TENANT_ID = 'XXXXX'
CLIENT = 'YYYY'
KEY = 'ZZZZ'
credentials = ServicePrincipalCredentials(client_id = CLIENT,secret = KEY,tenant = TENANT_ID)
subscription_id = 'abcde'
billing_client = BillingManagementClient(credentials, subscription_id)
billing_config = BillingManagementClientConfiguration(credentials, subscription_id)
serializer = Serializer()
deserializer = Deserializer()
billing_operation = BillingPeriodsOperations(billing_client, billing_config, serializer, deserializer)
for billing_period in billing_operation.list():
print billing_period.id

Executing the above throws the error:
