How to use the pykeepass.kdbx_parsing.KDBX function in pykeepass

for (database, password, transformed_key,
             keyfile, encryption_algorithm, kdf_algorithm, version) in zip(
                 databases, passwords, transformed_keys,
                 keyfiles, encryption_algorithms, kdf_algorithms, versions
