def upload_blob(filename: str, container: str, data: BinaryIO):
    try:
        blob_client = blob_service_client.get_blob_client(
            container=container, blob=filename)

        blob_client.upload_blob(data)

        print("success")
    except Exception as e:
        print(e.message)

Download Blob

def download_blob(filename: str, container: str):
    try:
        blob_client = blob_service_client.get_blob_client(
            container=container, blob=filename)

        print(blob_client.download_blob().readall())
    except Exception as e:
        print(e.message)

Delete Blob

def delete_blob(filename: str, container: str):
    try:
        blob_client = blob_service_client.get_blob_client(
            container=container, blob=filename)
        blob_client.delete_blob()
        print("success")
    except Exception as e:
        print(e.message)

Methods for Containers (Folders)

Create Container

def create_container(container: str):
    try:

    except Exception as e:
        print(e.message)

Delete Container

def delete_container(container: str):
    try:

    except Exception as e:
        print(e.message)
