 # SCRIPT EXPLANATION:
 #
 # This program is to assist me to write down a list of what hot drink they want (Coffee, Hot Chocolate)
 # Available hot drinks are 'Flat white, Decaf, Cappucino, Latte, and hot chocolate.
 # I need to capture: employee names, type of drink, and number of drinks.
 # I need to print a confirmation; capturing order, amount and their names.
 # Stretch Goal: we want to display a total number of type of drinks and count of drinks across all employees

 # To keep track of all the input I use a list of dictionaries of the following format
 #
 # an order has the following format:
 # [{
 #   'employee_name': "Name of employee",
 #   'order_items': {
 #       'type_of_drink': "name of drink, i.e. latte",
 #       'count': 1-3,
 #   },
 # }, ...
 # ]
 #

 # we are storing items available to order in a dictionary
 # to have an extensible way to store the menu information


 order_menu = {1: "Flat White", 2: "Decaf", 3: "Cappucino", 4: "Hot Chocolate", 5: "Latte"}

 # POTENTIAL ISSUES:
 #
 # 1) You can enter the same employee name multiple times, but it will capture them without overwriting
 # 2) You can choose the same drink multiple times for the same person and it will overwrite previous line items
 # 3) You can exceed the 3 maxx drink limit

 # Todo:
 # 1) Have a price for the drinks
 # 2) Have total price per person
 # 3) Have a overall price

 # pip install tinydb
 # pip install pprint

 # COMMENTS RE LINTING:
 # a line length of 80 is not a sensible default in 2020 anymore,
 # most development teams usually have a default for max line lenght of 120 or 160 even
 # pycodestyle --max-line-length=120 --verbose coffeerun.py ; echo $?
 # will return 0 (for success)
 # also E302 (2 blank spaces between comment and function head) is very commonly ignored


 # The purpose of this block of code is to show a banner to show customors where to look
 # by defining 'topbanner' it'll make the coding easier
