python read file and output into format string

Question

I have a sample json file example below

    {
      "email": "string",
      "cont_pic": "string",
      "title": "string",
      "user_cd": "string",
      "type4": "string"
    }

and want to convert into a formatted string like example below , it will convert into public static XX= 'yy';
Where XX is the Upper case of yy

  public static EMAIL= 'email';
  public static CONTACT_PIC = 'cont_pic';
  public static TITLE = 'title';
  public static USER_CODE = 'user_cd';
  public static TYPE4 = 'type4';

I have stuck at below code

filename = "file.json"
with open(filename) as f:
    contents = f.read()
    contents = contents.split(':')
    print(contents)

this is not a textfile so you can't parse it with just f.read() ! you should parse json i recommend you to study about json in python first. check below link : w3schools.com/python/python_json.asp — Ali

You can make use of the json module to parse the JSON file in Python like I did below:

import json

with open("file.json", "r") as f:
    data = json.loads(f.read())

    for key in data:
        print(f"public static {key.upper()} = '{key}';")

Output:

public static EMAIL = 'email';
public static CONT_PIC = 'cont_pic';
public static TITLE = 'title';
public static USER_CD = 'user_cd';
public static TYPE4 = 'type4';

this work great! if I have a json field like "serviceChanged": true, how can I based on the camel case to convert it become public static SERVICE_CHANGED= 'serviceChanged';
