I need to create a shopping list array in python that does these things (seven items minimum): Create three global variables with the proper data types( sub_total, total_price, sales_tax) Sales tax is 8.9% Create a shopping (List, Tuple or Dictionary) of your choice (Items in list) Create a price list (Price for each item in shopping list) Create and print your parallel array (match each item to its price) Print the list with its index numbers Select one or more items from the shopping list using the index number Print your selected items with price Print sub total (base price of item(s) before tax) Print sales tax amount (before adding it into total price) Calculate and print total price with tax included. Round to two decimal points

I need to create a shopping list array in python that does these things (seven items minimum):

1. Create three global variables with the proper data types( sub_total, total_price, sales_tax)
2. Sales tax is 8.9%
3. Create a shopping (List, Tuple or Dictionary) of your choice (Items in list)
4. Create a price list (Price for each item in shopping list)
5. Create and print your parallel array (match each item to its price)
6. Print the list with its index numbers
7. Select one or more items from the shopping list using the index number
8. Print your selected items with price
9. Print sub total (base price of item(s) before tax)
10. Print sales tax amount (before adding it into total price)
11. Calculate and print total price with tax included.
12. Round to two decimal points

This is what I have so far:

print("Hello! Welcome to Garrick's convenience store!\n" "Our menu is:\n" "Chips(1): $2.00\n" "Candy(2): $1.50\n" "Beef Jerky(3): $5.00\n" "Gum(4): $1.00\n"
"Soda(5): $3.00\n" "Gatorade(6): $3.00\n" "Bottled Water(7): $1.50")

def main():
menu = ['Chips', 'Candy', 'Beef Jerky', 'Gum', 'Soda', 'Gatorade', 'Bottled Water']
index_numbers = ['1', '2', '3', '4', '5', '6', '7']
shopping_list = input('Please enter the index number of the items you want to buy: ')

print('You have selected: ', shopping_list)

I have no idea what to do after this point.
