如何从原始json中获取仅具有唯一值的新json？

import json

def get_unique_json(original_json):
    data = json.loads(original_json)
    unique_values = set()
    new_data = {}

    for key, value in data.items():
        if value not in unique_values:
            unique_values.add(value)
            new_data[key] = value

    new_json = json.dumps(new_data)
    return new_json

# 示例用法
original_json = '{"name": "John", "age": 30, "city": "New York", "country": "USA", "language": "English"}'
new_json = get_unique_json(original_json)
print(new_json)
