how to access json object in python code example

Example 1: python read json file

import json

with open('path_to_file/person.json') as f:
  data = json.load(f)

print(data)

Example 2: load json

import json

with open('data.txt') as json_file:
    data = json.load(json_file)

Example 3: how to get specific data from json using python

with open('distros.json', 'r') as f:
    distros_dict = json.load(f)

for distro in distros_dict:
    print(distro['Name'])

Example 4: python import json data

# Basic syntax:
import ast
# Create function to import JSON-formatted data:
def import_json(filename):
  for line in open(filename):
    yield ast.literal_eval(line)
# Where ast.literal_eval allows you to safely evaluate the json data.
# 	See the following link for more on this:
# 	https://stackoverflow.com/questions/15197673/using-pythons-eval-vs-ast-literal-eval
        
# Import json data
data = list(import_json("/path/to/filename.json"))

# (Optional) convert json data to pandas dataframe:
dataframe = pd.DataFrame.from_dict(data)
# Where keys become column names

Example 5: read json data from file

// consider your file data is something like json string but aving parse issue 
//that means some additional char is there 
fs.readFile(ROLES_FILE, "utf8", (err, data) => {
      if (err) {
        res.status(403).json({});
      }
      const [localScope, action] = scope.split(".");
      const mapper = JSON.parse(data.toString("utf8").replace(/^\uFEFF/, ""));
      const isAllowed = checkRole(mapper, localScope, action, role);
      if (isAllowed) {
        next();
      } else {
        res.status(403).json({});
      }
