Thanks for the gist, I've made the following changes:

1. Added Python 3 support.
2. Improved error handling.
3. Support for more types of DNS records.
4. Refactored code to break out of loops sooner and stop casting everything as a str.
5. Added argparse to validate command line arguments.
6. Option to choose either the default or cloudflare output format.
7. Autodetect domain name from JSON instead of providing it as a command line argument.
