Following line of code:

block_blob_service = BlockBlobService(account_name = account_name,account_key  = account_key)

is actually creating an instance of BlockBlobService (not sure if creating instance is the correct term :), coming from .Net world) and nothing else.

In order to check if the account name/account key combination is correct, you will actually need to perform an operation on that storage account as there is no Login kind of operation supported in Azure Storage.

Normally the way I do it is try to list blob containers from that storage account. When listing blob containers, just set the num_results parameter to 1 as we are only interested in checking the account name/key validity and nothing else.

There are three possible outcomes:

  1. Account name/key is correct: In this case you would not get any errors.
  2. Account name is incorrect: In this case you will get remote name could not be resolved error.
  3. Account key is incorrect: In this case you will get a 403 error back from the service.

Using these outcomes you can decide whether or not account name/key combination is valid.
