In https://github.com/MicrosoftDocs/azure-docs-sdk-python/blob/master/docs-ref-services/data-lake-analytics.md, the example given is with outdated API:

from azure.mgmt.datalake.analytics.account.models import DataLakeAnalyticsAccount, DataLakeStoreAccountInfo

DataLakeStoreAccountInfo has been updated to DataLakeStoreAccountInformation, per https://github.com/Azure/azure-sdk-for-python/blob/430c1a7b95d2910bebf7f89469757b24587c893a/azure-mgmt-datalake-analytics/HISTORY.rst#040-2018-02-12
