pprint dictionary on multiple lines

Use width=1 or width=-1:

In [33]: pprint.pprint(a, width=1){'first': 123, 'second': 456, 'third': {1: 1,           2: 2}}

python python-2.7 dictionary pprint

You could convert the dict to json through json.dumps(d, indent=4)

print(json.dumps(item, indent=4)){    "second": 456,    "third": {        "1": 1,        "2": 2    },    "first": 123}

python python-2.7 dictionary pprint

If you are trying to pretty print the environment variables, use:

pprint.pprint(dict(os.environ), width=1)
