如何在python中漂亮地打印其值也是json字符串的json字符串

import json

def pretty_print_json(json_str):
    try:
        parsed_json = json.loads(json_str)
        pretty_json = json.dumps(parsed_json, indent=4, sort_keys=True)
        print(pretty_json)
    except json.JSONDecodeError as e:
        print("Invalid JSON string:", e)

# 示例调用
json_string = '{"name": "John", "age": 30, "city": "New York"}'
pretty_print_json(json_string)
