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

### Fixing Broken JSON Objects in Python Here's a Python function called `fix_json` that fixes broken JSON objects and returns the parsed object. This function utilizes Python's built-in `json` and `re` (regular expression) modules to replace incorrect parentheses and single quotes with their correct counterparts.

import json
import re

def fix_json(json_str):
    """
    Fixes broken JSON objects and returns the parsed object.

    Args:
        json_str (str): The broken JSON object as a string.

    Returns:
        dict: The parsed and fixed JSON object.
    """
    # Replace incorrect single quotes with double quotes
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)

    # Replace incorrect parentheses with square brackets
    json_str = re.sub(r"(\w+):\s*\(([^)]+)\)", r'"\1": [\2]', json_str)

    # Replace False/True with false/true
    json_str = re.sub(r"(\s+)True(\s*)", r'\1true\2', json_str)
    json_str = re.sub(r"(\s+)False(\s*)", r'\1false\2', json_str)

    # Parse the fixed JSON object
    try:
        fixed_json = json.loads(json_str)
        return fixed_json
    except json.JSONDecodeError as e:
        print(f"Error parsing JSON: {e}")
        return None

# Example usage:
broken_json = "{'a': (5, 4), 'b': True, 'c': False}"
fixed_json = fix_json(broken_json)
print(fixed_json)

### Notes: * This implementation uses regular expressions to replace incorrect single quotes and parentheses. It also replaces `True` and `False` with `true` and `false`, respectively. * The `fix_json` function attempts to parse the fixed JSON object using `json.loads()`. If parsing fails, it catches the `JSONDecodeError` exception and returns `None`. * You can modify this function to handle additional broken JSON issues by adding more regular expression replacements or using other string manipulation techniques.

Extract Code

I extracted the following code from that output:

import json
import re

def fix_json(json_str):
    """
    Fixes broken JSON objects and returns the parsed object.

    Args:
        json_str (str): The broken JSON object as a string.

    Returns:
        dict: The parsed and fixed JSON object.
    """
    # Replace incorrect single quotes with double quotes
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)

    # Replace incorrect parentheses with square brackets
    json_str = re.sub(r"(\w+):\s*\(([^)]+)\)", r'"\1": [\2]', json_str)

    # Replace False/True with false/true
    json_str = re.sub(r"(\s+)True(\s*)", r'\1true\2', json_str)
    json_str = re.sub(r"(\s+)False(\s*)", r'\1false\2', json_str)

    # Parse the fixed JSON object
    try:
        fixed_json = json.loads(json_str)
        return fixed_json
    except json.JSONDecodeError as e:
        print(f"Error parsing JSON: {e}")
        return None

# Example usage:
broken_json = "{'a': (5, 4), 'b': True, 'c': False}"
fixed_json = fix_json(broken_json)
print(fixed_json)

Run Code Interpreter

Running the following program:

import json
import re

def fix_json(json_str):
    """
    Fixes broken JSON objects and returns the parsed object.

    Args:
        json_str (str): The broken JSON object as a string.

    Returns:
        dict: The parsed and fixed JSON object.
    """
    # Replace incorrect single quotes with double quotes
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)
    json_str = re.sub(r"(\w+):", r'"\1":', json_str)

    # Replace incorrect parentheses with square brackets
    json_str = re.sub(r"(\w+):\s*\(([^)]+)\)", r'"\1": [\2]', json_str)

    # Replace False/True with false/true
    json_str = re.sub(r"(\s+)True(\s*)", r'\1true\2', json_str)
    json_str = re.sub(r"(\s+)False(\s*)", r'\1false\2', json_str)

    # Parse the fixed JSON object
    try:
        fixed_json = json.loads(json_str)
        return fixed_json
    except json.JSONDecodeError as e:
        print(f"Error parsing JSON: {e}")
        return None

# Example usage:
broken_json = "{'a': (5, 4), 'b': True, 'c': False}"
fixed_json = fix_json(broken_json)
print(fixed_json)





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
Error parsing JSON: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
Traceback (most recent call last):
  File "/usr/src/app/main.py", line 49, in <module>
    assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
           ^^^^^^^^^^^^^^^^^^
AssertionError: Wrong answer; got None instead of {'a': 5.0, 'b': [True, 4]}
