New to coding and need help implementing this function I cannot import any other libraries beside the one I was given which is import json.

import json

def read_json(filename): """ Returns the contents read from the JSON file filename. This function reads the contents of the file filename, and will use the json module to covert these contents into a Python data value. This value will either be a a dictionary or a list. Parameter filename: The file to read Precondition: filename is a string, referring to a file that exists, and that file is a valid JSON file """ pass # Implement this function

Below are the 2json files I was given
