Topic: Files I/O

assume that the .txt file will be formatted as follows:

food name calories food_type $price 

food name calories food_type $price ... 

There will be a line with the name of the food item followed by a line with the amount of calories, the type of food, and the price. The file may contain a variable number of empty lines between each food item

An example file could be formatted as follows:

Chicken Parm 710 Entree $17.50

gelato 100 dessert $4.00

Function name : split_bill Parameters : file (str), num_ppl (int), order (list), tip (float) Returns: float Description : Write a function which calculates how much each person in a group needs to pay for dinner. Your code should take into account the price of each food in the order list and then factor in the tip. The tip will be between 0 and 1 inclusive. A tip of 0.15, for example, represents a 15% tip. The total bill should be split evenly between num_ppl. Return how much each person should pay rounded to 2 decimal places. You can assume that num_ppl will be greater than 0.

Test Cases:

>>> split_bill('olive_garden.txt',2,['cheese Ravioli', 'tiramisu'],0.17) 11.28 

>>> split_bill('olive_garden.txt',3,['DIP DUO','salmon','zeppoli','SMores layer CAKE'],0.20) 11.36
