The python pretty-print system was once the default outputter. It simply passes the return data through to pprint.pformat and prints the results.
pprint.pformat
Example output:
{'saltmine': {'foo': {'bar': 'baz', 'dictionary': {'abc': 123, 'def': 456}, 'list': ['Hello', 'World']}}}
salt.output.pprint_out.
