  type        = "zip"
  source_file = "lambda.py"
  output_path = "lambda-${random_string.random.result}.zip"
}

I think it is a good idea to include the hash (md5 checksum) of its contents in the name of the archive. Then you can verify if the file content is compatible with the archive without having to unpack it.
