这是我正在处理的JSON文件。而且，我想吸引姓名，纬度，经度和城市名称。
results = requests.get(url).json()
results
names=county_merge['county']
la=county_merge['lat']
ln=county_merge['lng']
venues_list = []
venues_list.append([(
names,
la,
ln,
v['response']['venues'][0]['name'],
v['response']['venues'][0]['location']['lat'],
v['response']['venues'][0]['location']['lng'],
v['response']['venues'][0]['location']['city']) for v in results])
我希望这会给我几行内容。 [县名，38.xxxx，-120.xxxx，XXX兽医诊所，38.xxxx，-120.xxxx，圣地亚哥] [县名，38.xxxx，-120.xxxx，XXX兽医诊所，38.xxxx，-120.xxxx，圣地亚哥] [县名，38.xxxx，-120.xxxx，XXX兽医诊所，38.xxxx，-120.xxxx，圣地亚哥] [县名，38.xxxx，-120.xxxx，XXX兽医诊所，38.xxxx，-120.xxxx，圣地亚哥] [县名，38.xxxx，-120.xxxx，XXX兽医诊所，38.xxxx，-120.xxxx，圣地亚哥] 。 。 。
但是，这只会给我带来错误和沮丧。

您有解决此代码的想法吗？
答案 0 :(得分：2)
[v for v in results]
给你
['meta', 'response']
因此，您得到了结果键，即字符串。我想你要
venues_list.append([(
names,
la,
ln,
v['name'],
v['location']['lat'],
v['location']['lng'],
v['location']['city']) for v in results['response']['venues'])
