如何在python中读取json对象 [英] how to read json object in python

问题描述

我有一个名为"panamaleaks50k.json"的json文件.我想从json文件中获取['text']字段，但显示以下错误

i have json file named "panamaleaks50k.json" . I want to get ['text'] field from json file but it shows me following error

JSON对象必须是str，bytes或bytearray，而不是'TextIOWrapper'

the JSON object must be str, bytes or bytearray, not 'TextIOWrapper'

这是我的代码

with open('C:/Users/bilal butt/Desktop/PanamalEakJson.json','r') as lst:
    b = json.loads(lst)
    print(b['text'])

我的json文件外观

[
{
   "fullname": "Mohammad Fayyaz",
   "id": "885800668862263296",
   "likes": "0",
   "replies": "0",

 },

  "url": "/PtiTeampakistan/status/885800910357749761",
  "user": "PtiTeampakistan"
 }
]

我如何才能读取所有['text']和仅一个['text']字段?

how i can read all ['text'] and just single ['text'] field?

推荐答案

您应该将文件 contents (即字符串)传递给json.loads()，而不是文件对象本身.试试这个:

You should pass the file contents (i.e. a string) to json.loads(), not the file object itself. Try this:

with open(file_path) as f:
    data = json.loads(f.read())
    print(data[0]['text'])

还有 json.load() 函数，该函数接受文件对象，并在后台为您执行f.read()部分.
