python - 访问列表中字典中的元素

问题描述

这段代码的目的是发送一个 http get 请求，我想从请求的结果中获取其中一个键的值。作为示例，我想获取“目标”的值，请参见下面的预期行为：

request = request.get(url,auth=(user,password))

all_results = request.text

print(all_results)
>>> {"thing":[{"thing1":1,"thing2":2,"thing3":3,"thing4":4,"thing5":5,"thing6":{"t1":0,"t2":2,"t3":0,"t4":0,"t5":0,},"target":"I WANT THIS"}],"l":{"m":1,"n":1,"o":0}}

x = all_results["thing"][0]["transactions"]

print(x) 
>>> "I WANT THIS"

但是当我打印 x 时，我得到一个错误：

TypeError: string indices must be integers

标签： pythonpython-3.xlistdictionaryhttp-get

解决方案

利用my_dict["things"][0]["target"]

完整代码：

mydict = {"things":
        [
            {
                "thing1":"a",
                "thing2":"b",
                "thing3":{
                    "something1":"c",
                    "something2":"d"
                    },
                "target":"I WANT THIS"
            }
        ],
    "somethingelse":"z"
} 

x = mydict ["things"][0]["target"]

print(x)
 
>> I WANT THIS
