读取json文件并获取输出值 [英] Read json file and get output values

问题描述

我想使用python获取以下json文件的输出

I want to fetch the output of below json file using python

Json文件

{
    "Name": [
        {
            "name": "John",
            "Avg": "55.7"
        },
        {
            "name": "Rose",
            "Avg": "71.23"
        },
        {
            "name": "Lola",
            "Avg": "78.93"
        },
        {
            "name": "Harry",
            "Avg": "95.5"
        }

    ]
}

当我寻找哈利时，我想获得该人的平均分数 即我需要以下或类似格式的输出

I want to get the average marks of the person, when I look for harry i.e. I need output in below or similar format

Harry = 95.5

这是我的代码

import json

json_file = open('test.json')  //the above contents are stored in the json
data = json.load(json_file)
do = data['Name'][0]
op1 = do['Name']
if op1 is 'Harry':
    print do['Avg']

但是当我运行时，出现错误IOError: [Errno 63] File name too long.

But when I run I get error IOError: [Errno 63] File name too long.

推荐答案

您可以执行以下简单操作

You can do something simple like this

import json

file = open('data.json')
json_data = json.load(file)

stud_list = json_data['Name']
y = {}
for var in stud_list:
    x = {var['name']: var['Avg']}
    y = dict(list(x.items()) + list(y.items()))

print(y)

它以字典格式给出输出

{'哈利':'95 .5'，'萝拉':'78 .93'，'罗斯':'71 .23'，'约翰':'55 .7'}

{'Harry': '95.5', 'Lola': '78.93', 'Rose': '71.23', 'John': '55.7'}
