Question

I have some files stored in Azure Storage ,and I want to iterate and read them from azure function (in python) How should I do that?

Answer 1

You can use below code to loop through all the containers and directories present in the Storage account.

import os
from azure.storage.blob import BlockBlobService

ACCOUNT_NAME = "<ACCOUNT_NAME>"
SAS_TOKEN='<SAS TOKEN>'

blob_service = BlockBlobService(account_name=ACCOUNT_NAME,account_key=None,sas_token=SAS_TOKEN)

print("\nList blobs in the container")
containers = blob_service.list_containers() #lists the containers
for cntnr in containers:
    generator = blob_service.list_blobs(cntnr.name) #lists the blobs inside containers
    for blob in generator:
        print("\t Blob name: "+cntnr.name+'/'+  blob.name)
        file=blob_service.get_blob_to_text(cntnr.name,blob.name) #lets you read content directly
        file=blob_service.get_blob_to_path(cntnr.name,blob.name,blob.name) #lets you download the content to local and from there you can read the file
