Initial Query

Write me a python function called fix_json that fixes broken JSON objects, and returns the parsed object. I'll pass the JSON object as a string and it should fix: - Incorect parenthesis, e.g., {"a": (5, 4)} -> {"a": [5, 4]} - Incorrect single quotes, e.g., {'a': 5} -> {"a": 5} - False/True -> false/true Make sure not to break data inside strings! So if there's a True or a ( inside a string keep them the way they are. Also don't break quoted strings

In this code: * We first replace incorrect single quotes with double quotes using regular expressions. * Then, we replace incorrect parentheses with brackets. * Next, we replace incorrect boolean values (`True`/`False`) with lowercase versions (`true`/`false`). * After that, we replace incorrect single quotes inside objects. * Finally, we parse the fixed JSON object using the `json.loads()` function. Note: This function assumes that the input JSON string is well-formed except for the specified issues. If the input string has other issues, the function may not work correctly.

answer = fix_json('''{"a": 5, "b": [3, 4]}''')
expected = {"a": 5, "b": [3, 4]}
assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'

answer = fix_json('''{'a': 5.0, 'b': (True, 4)}''')
expected = {"a": 5.0, "b": [True, 4]}
assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'

answer = fix_json('''{'True': False, 'b()': (3, 4), "c'": []}''')
expected = {"True": False, "b()": [3, 4], "c'": []}
assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
print('All tests passed')

And got the output:

Error parsing JSON: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
None

           ^^^^^^^^^^^^^^^^^^
