move or copy files(blob) between storage accounts python (azure function)?

Question

I want to move (or copy then delete) files/blobs between two storage accounts using python (in an azure function). I've used methods like this. However this works for older SDKs, does anyone know a way for new SDK?

Something like this but between two storage accounts rather than containers.

if you use the first link I mentioned, I'll get : no module name .make_blob_url and early on in the code cannot import name 'BlockBlobService' — mas
Have you referred to github.com/Azure/azure-sdk-for-python/blob/master/sdk/storage/…? — Jim Xu
yeah, how do you get the link for source blob. here is hard coded — mas
Now. You want to know how get make source blob URL. Right? Let me test it. — Jim Xu

If you want to copy blob across Azure storage account, please refer to the following code

from azure.storage.blob import ResourceTypes, AccountSasPermissions, generate_account_sas, BlobServiceClient
from datetime import datetime, timedelta
source_key = ''
des_key = ''
source_account_name = ''
des_account_name = '23storage23'
# genearte account sas token for source account
sas_token = generate_account_sas(account_name=source_account_name, account_key=source_key,
                                 resource_types=ResourceTypes(
                                     service=True, container=True, object=True),
                                 permission=AccountSasPermissions(read=True),
                                 expiry=datetime.utcnow() + timedelta(hours=1))
source_blob_service_client = BlobServiceClient(
    account_url=f'https://{source_account_name}.blob.core.windows.net/', credential=source_key)
des_blob_service_client = BlobServiceClient(
    account_url=f'https://{des_account_name}.blob.core.windows.net/', credential=des_key)

source_container_client = source_blob_service_client.get_container_client(
    'copy')

source_blob = source_container_client.get_blob_client('Capture.PNG')
source_url = source_blob.url+'?'+sas_token
# copy
des_blob_service_client.get_blob_client(
    'test', source_blob.blob_name).start_copy_from_url(source_url)

Besides, if the access level of the source container is public, we can simplify the code as below

from azure.storage.blob import BlobServiceClient
source_key = ''
des_key = ''
source_account_name = ''
des_account_name = '23storage23'
source_blob_service_client = BlobServiceClient(
    account_url=f'https://{source_account_name}.blob.core.windows.net/', credential=source_key)
des_blob_service_client = BlobServiceClient(
    account_url=f'https://{des_account_name}.blob.core.windows.net/', credential=des_key)

source_container_client = source_blob_service_client.get_container_client(
    'input')

source_blob = source_container_client.get_blob_client('file.json')
source_url = source_blob.url
# copy
des_blob_service_client.get_blob_client(
    'test', source_blob.blob_name).start_copy_from_url(source_url)
