if __name__ == "__main__":
    import sys
    import json

    file_name = sys.argv[1]

    try:
        file = open(file_name, 'r')
    except IOError:
        print("File not accessible")

    dns_info = json.loads(file.read());
    
    zones = parse_dns_info(dns_info)
    for zone in zones:
        print "\t".join(zone)

Thanks for forking/sharing this - worked great for me, except I had to add:
domain = sys.argv[2]
after the file_name = line.

@mbafford you don't need to provide the domain, its already in the JSON file, you can get it as follows:

domain = dns_info['Result']['DomainBasicDetails']['DomainName']

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.
