Step 9 - “Display restaurant expense rating” option

New functions needed:

• get_restaurant_expense_rating()

For this menu item, in your main program, you will use the restaurant menu list. This part of your main program will call the function get_restaurant_expense_rating().

def get_restaurant_expense_rating(restaurant_menu_list):
    """
    param: restaurant_menu_list - a list of restaurants and their dishes (list of dicts)
    
    Computes the average price of all the items on the menu and display the expense rating of the restaurant.
    average_price < 10 -> Expense rating is : $
    10 <= average_price < 20 -> Expense rating is : $$
    average_price >= 20: Expense rating is : $$$
    
    returns: the average price of the items as a float
    """

You are NOT allowed to use any import statements or outside library methods in get_restaurant_expense_rating()).

You can only use “regular” Python methods for this function.

Here are some hints on how to go about this:

• You should collect all the menu items’ prices for a given restaurant into one list.
• You’ve done calculating means (averages) from lists before…
