If you use json.dumps() in order to write a json into a file, it will be wriiten all in one line. You can do more with dumps(). You can pretty print into the file with indentation using indent parameter:

dumped_json = json.dumps(json.loads(content), indent=4)

You can do more and sort json keys! To do that pass sort_keys to dumps function like below:

dumped_json = json.dumps(json.loads(content), indent=4, sort_keys=True)

#python #json #dumps #indent #sort #sort_keys

As an alternative to the pprint module:

# The standard string repr for dicts is hard to read:
>>> my_mapping = {'a': 23, 'b': 42, 'c': 0xc0ffee}
>>> my_mapping
{'b': 42, 'c': 12648430. 'a': 23}  # 😞


# The "json" module can do a much better job:
>>> import json
>>> print(json.dumps(my_mapping, indent=4, sort_keys=True))
{
    "a": 23,
    "b": 42,
    "c": 12648430
}

# Note this only works with dicts containing
# primitive types (check out the "pprint" module):
>>> json.dumps({all: 'yup'})
TypeError: keys must be a string

#python #pprint #json #dumps
