def datalake_download(CONNECTION_STRING, file_system, source_path, source_file):
    service_client = DataLakeServiceClient.from_connection_string(CONNECTION_STRING)
    file_system_client = service_client.get_file_system_client(file_system=file_system)
    directory_client = file_system_client.get_directory_client(source_path)
    file_client = directory_client.get_file_client(source_file)
    download = file_client.download_file()
    downloaded_bytes = download.readall()
    return downloaded_bytes

where CONNECTION_STRING is an environmental variable.
