Answer 1

download_blob() download the blob to a StorageStreamDownloader class, and in this class there is a download_to_stream, with this you will get the blob stream.

from azure.storage.blob import BlobServiceClient, BlobClient, ContainerClient
from io import BytesIO
import PyPDF2
filename = "test.pdf"

container_name="test"

blob_service_client = BlobServiceClient.from_connection_string("connection string")
container_client=blob_service_client.get_container_client(container_name)
blob_client = container_client.get_blob_client(filename)
streamdownloader=blob_client.download_blob()

stream = BytesIO()
streamdownloader.download_to_stream(stream)

fileReader = PyPDF2.PdfFileReader(stream)

print(fileReader.numPages)

And this is my result. It will print the pdf pages number.
