Question

所以我一直在解析通过谷歌api获得的JSON数据中的信息。我试图解析地址信息，我成功地做了大部分地址信息，除了字段“位置”，每次运行它都给我这个错误TypeError：字符串索引必须是整数之后。

这是data = json.loads（requests.get（request）.text）的打印输出

我尝试打印出该字段的组件方面，然后在错误发生后打印出“位置”。我不知道该怎么做以及如何继续解析我需要的信息。任何人都可以提供答案谢谢！

这是我的脚本，部分是在下面的位置字段开始给出错误。

Answer 1

问题是row['geocode_data']['geometry']会返回包含您的位置和内容的字典。因此，当您将字典迭代为 -

时

for component in row['geocode_data']['geometry']:
    if component['location']:
        df['location_lng'][i] = component['location']['lng']
        df['location_lat'][i] = component['location']['lat']

component是字典中的键（不是字典本身），它是一个字符串，因此当你执行 - component['location']时，它会导致错误。显示相同错误的一个非常简单的示例 -

>>> for i in d:
...     i['1']
...
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: string indices must be integers
>>> for i in d:
...     print(i)
...
1

对于您的情况，您不需要遍历字典，只需要将字典设置为组件，如果组件中有location，则取其值，示例 -

component = row['geocode_data']['geometry']:
if 'location' in component:
    df['location_lng'][i] = component['location']['lng']
    df['location_lat'][i] = component['location']['lat']

使用python和google api从反向地理编码数据中解析所选信息
