Create a program in Python that reads data from Breakfast Menu (https://www.w3schools.com/xml/simple.xml) and builds parallel arrays for the menu items, with each array containing the menu item name, description, calories, and price, respectively. After reading the data and building the arrays, display the menu items similar to the following:

name - description - calories - price

At the bottom, display the total number of items on the menu, the average number of calories per item, and the average price per item similar to:

0 items - 0 average calories - 0ドル.00 average price

You may either read the page using Internet processing methods, or you may download and save the page and then read the data from the saved file. You must process the data using string functions (no XML libraries).

must use separate subroutines/functions/methods to implement each type of processing, and include error handling for missing or invalid data.
