无法在 python 中格式化 a.json 文件

Question

I have a python code (main.py) which contains a python module named json which I want to use to store some important key=value pairs in a comfortable manner, that I can use later. The problem is here that the format(structure) .

For your better understanding I have attached some code here

The main.py file contains the main code. The output.json file shows the output of the main file. The expected_output.json file contains the format(structure) which shows that how I want to store my data(key=value) in general.

If anyone is interested to fork this repository he/she is extreamly invited.

The code: main.py

any one please solve this error

Answer 1

You cannot append an Object to an Object like how the output.json looked like.

I changed this data[_acc_Name].append(_info) to the following:

if len(data[_acc_Name]) == 0:
    print('no user for this account')
    data[_acc_Name].append([_info])
else:
    print('users exist for this account')
    data[_acc_Name].append(_info[_acc_Name])

Got this output

{
  "facebook": [
    {
      "name": "yul",
      "email": "noooo@no.com",
      "pass": "z8k7"
    },
    {
      "name": "abc",
      "email": "yyy@gmail.com",
      "pass": "4~R6|)$}"
    }
  ]
}

You might have to add some code to support new account though
