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

            raise ValueError(f"Could not fix JSON: {e}")
## How It Works 1. First attempts to parse the JSON directly (in case it's already valid) 2. If that fails, uses Python's `ast.literal_eval()` to parse the string as a Python literal 3. This handles single quotes and parentheses (tuples) naturally 4. Converts the Python object to a proper JSON string with `json.dumps()`, which: - Converts Python tuples to JSON arrays - Ensures all strings use double quotes - Converts Python's `True`/`False` to JSON's `true`/`false` 5. Finally parses the fixed JSON string back into a Python object ## Example Usage

# Fix parentheses
result = fix_json('{"a": (1, 2, 3)}')
print(result)  # {'a': [1, 2, 3]}

# Fix single quotes
result = fix_json("{'name': 'John', 'age': 30}")
print(result)  # {'name': 'John', 'age': 30}

# Fix boolean values
result = fix_json('{"active": True, "verified": False}')
print(result)  # {'active': True, 'verified': False}
This solution elegantly handles all the specified cases by leveraging Python's built-in modules.
