来自 JSON 的真实数据元素

Question

我正在尝试使用 python.Below 从 json url link 中提取数据元素是代码。当我尝试提取元素时它正在部分工作

 response = urllib.request.urlopen(url)
    data = json.loads(response.read())
    print("planId",data[0]["planId"]) #Gives result as planId PWR93173MBE1
    print("postcode",data[0]["postcode"]) # Gives result as postcode 2000
    print("tariffType", data[0]["tariffType"]) This gives me error.

还有，如果我想提取其他元素，比如PlanType等Fees中的其他字段，怎么办？

   [
       {
          "planData":{
             "planType":"M",
             "tariffType":"SR",

    ]

Answer 1

tariffType 属性位于 planData 属性内，因此您需要执行类似

的操作

print("tariffType", data[0]["planData"]["tariffType"])

Answer 2

你忘记嵌套了，正确的应该是：

print("tariffType", data[0]["planData"]["tariffType"])
