创建了一个字典,但是一些键值对似乎缺失或没有转移

我遇到了将json样式python代码转换为字典的问题。我正在使用来自Google的拉取位置数据并获取我需要的所有数据。但是,每当我从数据列表中创建字典时,都会丢失一些键:值对。

这是我回来的json样式python代码。

正如我在另一个thread 'price_level'中指出的那样,在'results'列表之外。但是,每当我呼叫“geocode_result.keys()'时,我只会获得'html_attributes', 'next_page_token', 'results', 'status'

这是我正在运行的代码。

results = []

# def get_data():
for term, (latitude, longitude, search_radius) in search_parameters.items():
    params = {
        'query': term,
        'location': (latitude, longitude),
        'radius': search_radius
    }
    geocode_result = gmaps.places(**params)
    for i in geocode_result['results']:

        results.append(i['name'])
        results.append(i['geometry']['location']['lat'])
        results.append(i['geometry']['location']['lng'])
        results.append(i['formatted_address'])
        results.append(i['opening_hours']['open_now'])
        results.append(i['price_level'])
        results.append(i['rating'])
        results.append(i['types'])

    if 'next_page_token' in geocode_result.keys():
        while 'next_page_token' in geocode_result.keys():
            time.sleep(2.5)
            params.update({'page_token': geocode_result['next_page_token']})
            geocode_result = gmaps.places(**params)
            for i in geocode_result['results']:
                results.append(i['name'])
                results.append(i['geometry']['location']['lat'])
                results.append(i['geometry']['location']['lng'])
                results.append(i['formatted_address'])
                results.append(i['opening_hours']['open_now'])
                results.append(i['price_level'])
                results.append(i['rating'])
                results.append(i['types'])
    else:
        break

print(results)

我希望能够提取'lat', 'lng', 'name', 'open_now', 'price_level', 'rating', 'types'。我可以调用除最后三个之外的所有内容,因为它们不会被存储为'geocode_result'中的键值对。任何帮助或建议表示赞赏!

答案 0 :(得分:0)

&#34;是的,但是你在geocode_result中搜索[&#39;结果&#39;]所以你应该在geocode_result中查找我[&#39;结果&#39;]:print i.keys( )&#34; - @aws_apprentice

但事实证明,我收到错误的原因是并非所有结果都有&#39; price_level&#39;所以我将使用try语句来避免这个问题。
