json decode and add a new data in python code example

Example 1: insert json file in python

a_dictionary = {"d": 4}

with open("sample_file.json", "r+") as file:
    data = json.load(file)	# get data from file
    update(a_dictionary)
    seek(0)
    json.dump(data, file)	# insert data in file

Example 2: 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:

# 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
