如何删除here autocomplete API返回的事实重复项

import requests

def remove_duplicate_results(api_key, search_query):
    url = f"https://autocomplete.geocoder.ls.hereapi.com/6.2/suggest.json?apiKey={api_key}&query={search_query}"
    response = requests.get(url)
    data = response.json()

    unique_results = []
    seen_results = set()

    for result in data['suggestions']:
        result_key = f"{result['label']}_{result['location']['lat']}_{result['location']['lng']}"
        if result_key not in seen_results:
            unique_results.append(result)
            seen_results.add(result_key)

    return unique_results

# 示例用法
api_key = "YOUR_HERE_API_KEY"
search_query = "123 Main Street"

unique_results = remove_duplicate_results(api_key, search_query)
print(unique_results)
