How to correctly read json file?

Question

Python

All the best!
I'm new to python, but in Google, somehow I couldn't find a suitable option for me, so don't judge strictly, but if you can tell me please :)
And so, I have a user_config.json file, it looks like this:

{
  "userId" : "0001",
  "userName": "user"
}

Trying to open and read it with python:

config =  open(os.path.join(os.path.dirname(__file__), 'user_config.json'), 'r')
confid_data = json.load(config)
print confid_data
config.close()

here is the result :
{u'userId': u'0001', u'userName': u'user'}
How do i remove the children u' so i can access the variable normally using the key :
confid_data.userId or confid_data.userName ?

Answer 1

Everything is correct.
u is the notation that the string is in Unicode. You are using the 2nd version of Python, there is a difference. In the third version, all strings are in Unicode, so there is no u character.

How can I remove these u' so that I can access the variable properly using the key :
confid_data.userId or confid_data.userName ?

You read a dictionary, and the elements of the dictionary are accessed using the [] operator or the get method.
confid_data['userId'] - throws a KeyError exception if there is no such key
confid_data.get('userId') - throws None (or whatever you pass as the second argument to the method) if there is no key.
Why confid_data?

Answer 2

use json.load s instead

Answer 3

import os
import json

config = {}
with open('user_config.json', 'r', encoding="utf-8") as cf:
    config = json.loads(cf.read())


print(config)  # {u'userName': u'user', u'userId': u'0001'}


print(config.get("userName"))  # user
print(config.get("userName1"))  # None

# но намного лучше использовать неизменяемую структуру данних
# namedtuple
from collections import namedtuple


with open('user_config.json', 'r', encoding="utf-8") as cf:
    config = json.loads(cf.read(), 
         object_hook=lambda d: namedtuple('CONFIG', d.keys())(*d.values()))


print(config.userName, config.userId)
