Feature Summary

When retrieving data like the following:

vars = client.hosts.get(name=hostname).results[0].get_related('variable_data')

The resulting data is return as a json structure:

{
    "node_availability": "active",
    "node_labels": {
        "ansible": "true"
    },
    "node_role": "worker",
    "remote_host_enabled": "true",
    "remote_host_id": 2504,
    "remote_tower_enabled": "true",
    "remote_tower_id": 2504,
}

However, when attempting to convert it to yaml using ruamel.yaml and the 'rt' or 'safe' dumper, this results in an error:

   vars = client.hosts.get(name=hostname).results[0].get_related('variable_data')
   yaml.dump(vars, sys.stdout)

raise RepresenterError(f'cannot represent an object: {data!s}')
ruamel.yaml.representer.RepresenterError: cannot represent an object: {

The 'unsafe' dumper will dump the objects but that data is not useful as yaml output.

Steps to reproduce

   vars = client.hosts.get(name=hostname).results[0].get_related('variable_data')
   yaml.dump(vars, sys.stdout)

Current results

ruamel.yaml.representer.RepresenterError: cannot represent an object: {

Sugested feature result

It would be nice if there was a way to indicate that yaml output was desired or a utility function that could convert the objects back to regular python data structures.

FYI, I still think it's a good idea but I was able to work around it by converting the entire output to a string and feeding the string to yaml.dump.
