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
I NEED HELP PLEASE
NO REGEX OR ANYTHING COMPLICATED PLEASE.. USE BASIC APPROACH
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 - $0.00 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.
THE BREAKFAST MENU IS BELOW:
WHAT I HAVE SO FAR BELOW:
def read_data():
with open("simple.xml", "r") as file:
string = file.read()
def extract_data(tag, string):
data = []
start_tag = f"<{tag}>"
end_tag = f"</{tag}>"
while start_tag in string:
start_index = string.find(start_tag) + len(start_tag)
end_index = string.find(end_tag)
value = string[start_index:end_index]
data.append(value)
string = string[end_index + len(end_tag):]
return data
def get_data():
names = extract_data("name", string)
prices = extract_data("price", string)
descriptions = extract_data("description", string)
calories = extract_data("calories", string)
def display_menu(names, descriptions, calories, prices):
for i in range(len(names)):
print(f"{names[i]} - {descriptions[i]} - {calories[i]} - {prices[i]}")
def display_stats(total_items, average_calories, average_price):
total_items = len(names)
average_calories = sum(map(int, calories)) / total_items
average_price = sum([float(price[1:]) for price in prices]) / total_items
print(f"\n{total_items} items - {average_calories:.1f} average calories - ${average_price:.2f} average price")
def main():
read_data()
extract_data(tag, string)
get_data()
display_stats(total_items, average_calories, average_price)
display_menu(names, descriptions, calories, prices)
main()
