Question

我有一个程序，我想从Google Places API收集单个数据。我能够获得我想要的大部分属性，但是，当我尝试获取＆＃39; html_attributions＆＃34;时，我收到错误：

    TypeError: list indices must be integers, not str

我使用了与此行相同的格式，因此我不理解它为什么会抛出此错误。

这是我的代码：

    for n in range(len(data['results'])):
            location = []
            address = data['results'][n]['vicinity']
            address = address[: address.rfind(", ")]
            coords_lat = str(data['results'][n]['geometry']['location']['lat'])
            coords_lng = str(data['results'][n]['geometry']['location']['lng'])
            url_href = ''
            if str(data['results'][n]['photos']['html_attributions']):
                url_href = str(data['results'][n]['photos']['html_attributions'])
            location = [address, coords_lat, coords_lng, url_href]
            return location

这是JSON数据：

     "geometry" : {
        "location" : {
           "lat" : 43.3151516,

Answer 1

从查看有效负载，获取＆＃34; html_attributions＆＃34;，假设您的解析数据正确[＆＃39;] [n]（因为您没有显示整个json payload），你必须做类似

的事情

data['results'][n]['photos'][0]['html_attributions'][0]

试图在python中解析json文件中的href
