Create a Function to Generate a JSON File from a List of Names and Values

[hbisneto]

Develop a Python function that takes a list of item names and their corresponding values as parameters, iterates over the names, and creates a JSON file with the resulting structure. The function should associate each name with its respective value, producing a well-formatted JSON file.

Task Details:

• Objective: Create a function that:
  • Takes two parameters:
    • names: a list of strings representing the item names.
    • values: a list of values (can be any JSON-compatible type, such as strings, numbers, booleans, etc.).
  • Iterates over the list of names and associates each name with its corresponding value.
  • Generates a JSON file with the resulting structure.
• Requirements:
  • The function must validate that the names and values lists have the same length. If not, it should raise an exception with a clear message.
  • The generated JSON file must be saved to a specified path (either as an additional parameter or a default path).
  • The JSON file should be well-formatted (e.g., using indent=4 with the json library).
  • Ensure that the value types are JSON-compatible.
• Example Usage:

  names = ["item1", "item2", "item3"]
  values = [10, "text", True]
  create_json(names, values, "output.json")

  Expected Output (output.json):

  {
      "item1": 10,
      "item2": "text",
      "item3": true
  }

• Acceptance Criteria:
  • The function must correctly create the JSON file based on the provided parameters.
  • It should handle errors such as lists of different lengths or invalid data types.
  • The generated JSON file must be valid and readable.
  • Unit tests must be implemented to verify:
    • Correct creation of the JSON file.
    • Error handling for lists of different lengths.
    • Validation of JSON-compatible data types.
• Additional Notes:
  • Use Python's standard json library for JSON file manipulation.
  • Consider adding an optional parameter to specify the output file name/path.
  • Document the function with a docstring explaining parameters, return value, and possible exceptions.
