我试图解析上面的json数据,并通过这样做获得“zip”值

{
    "response": {
        "version": "0.1",
        "termsofService": "http://www.wunderground.com/weather/api/d/terms.html",
        "features": {
            "conditions": 1
        }
    },

    "current_observation": {
        "image": {
            "url": "http://icons.wxug.com/graphics/wu2/logo_130x80.png",
            "title": "Weather Underground",
            "link": "http://www.wunderground.com"
        },
        "display_location": {
            "full": "San Francisco, CA",
            "city": "San Francisco",
            "state": "CA",
            "state_name": "California",
            "country": "US",
            "country_iso3166": "US",
            "zip": "94102",
        }
    }
}
然后我会得到这个错误

j = json.loads(string)
keys = j.keys()
print(keys)
#current_observation

print(j['current_observation']['zip'])
回溯(最近一次呼叫最后一次):
文件“\wunder.py”,第17行,在
打印(j['current_observation']['zip'])
KeyError:'zip'

因此,我试图总结一下,解析JSON数据并获得zip值,但收效甚微

您错过了由
display\u location
映射的词典:

Traceback (most recent call last):
  File ".\wunder.py", line 17, in <module>
    print(j['current_observation']['zip'])
KeyError: 'zip'

print(keys)
提供了什么?如果无法确保JSON格式正确,请查看是否可以使用:
for key,value in j.items():print key,value
进行迭代。我发现JSON存在两个问题。将json放在问题中是:1-为
image
2添加一个右括号-删除
zip
后的逗号-您可以接受下面的正确答案。既然Json格式正确,您就可以看到它了。
print(j['current_observation']['display_location']['zip'])
