Formatting json cleanly

[Daring_T]

Daring_T here,
I have a dictionary that appends to a json file, and it outputs on one line.
Is there a way to cleanly format the json data like pprint.

Output:
{"11-19-20_9:18.31": { "a": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0], "b": [2, 2, 2, 0, 0, 0, 0, 0, 0, 0], "c": [3, 3, 3, 0, 0, 0, 0, 0, 0, 0], "d": [4, 4, 4, 4, 0, 0, 0, 0, 0, 0], "e": [5, 5, 5, 5, 5, 0, 0, 0, 0, 0], "g": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "h": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "i": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "j": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}, "11-19-20_17:20.5": { "a": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0], "b": [2, 2, 2, 0, 0, 0, 0, 0, 0, 0], "c": [3, 3, 3, 0, 0, 0, 0, 0, 0, 0], "d": [4, 4, 4, 4, 0, 0, 0, 0, 0, 0], "e": [5, 5, 5, 5, 5, 0, 0, 0, 0, 0], "g": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "h": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "i": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "j": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}}

This is the original json data

Output:
{"11-19-20_9:18.31": {"a": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0], "b": [2, 2, 2, 0, 0, 0, 0, 0, 0, 0], "c": [3, 3, 3, 0, 0, 0, 0, 0, 0, 0], "d": [4, 4, 4, 4, 0, 0, 0, 0, 0, 0], "e": [5, 5, 5, 5, 5, 0, 0, 0, 0, 0], "g": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "h": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "i": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "j": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}, "11-19-20_17:20.5": {"a": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0], "b": [2, 2, 2, 0, 0, 0, 0, 0, 0, 0], "c": [3, 3, 3, 0, 0, 0, 0, 0, 0, 0], "d": [4, 4, 4, 4, 0, 0, 0, 0, 0, 0], "e": [5, 5, 5, 5, 5, 0, 0, 0, 0, 0], "g": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "h": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "i": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "j": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}}

Here the code I have to add dicts to the json file.

import os import pprint from datetime import datetime def output_board_layout(input_file="battleship.json", add_to_key="_in_book"): """ :parameter input_file inputs json_data to file default is battleship.json add_to_key adds a string to the key :return: dict formatted to json """ battleship_grid = { "a": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "b": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "c": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "d": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "e": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "g": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "h": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "i": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], "j": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]} dt = datetime.today() key = f"{str(dt.month)}-{str(dt.day)}-{str(dt.year)[2:]}_{str(dt.hour)}:{str(dt.minute)}.{str(dt.second)}" key = key + add_to_key new_battleship_grid = dict() new_battleship_grid[key] = battleship_grid if os.stat(input_file).st_size != 0: # Checks if file is not empty with open(input_file, "r") as f: existing_json_data = json.load(f) existing_json_data.update(new_battleship_grid) print("\n" * 3) pprint.pprint(existing_json_data) json_file_data = json.dumps(existing_json_data) else: json_file_data = json.dumps(new_battleship_grid) with open(input_file, "w") as f: # json.dump(json_file_data, f) f.write(json_file_data) return json_file_data
