Copied unchanged from the base: screen set-up, key bindings, the animation loop with game_is_on, the eating check, the game-over check, the wait for a click and the quiet exit when the window is closed. main imports food and scoreboard only when it runs, so importing it needs neither turtle nor tkinter.
Task: MIL-002#5
Closes#12
Copied unchanged from the base: class Scoreboard(Turtle) with update_scoreboard, increase_score and game_over. MIL-003 checks the values against the day-21 lectures.
Task: MIL-002#4
Closes#11
Copied unchanged from the base: class Food(Turtle) with refresh, and one random_coordinate function that the tests replace. MIL-003 checks the values against the day-21 lectures.
Task: MIL-002#3
Closes#10
Copied unchanged from the base: create_snake, add_segment, extend, move, hits_wall, hits_tail, up, down, left and right, with the segments list and the head. The tail check loops over the slice segments[1:]. snake.py does not import turtle until a real segment is made.
Task: MIL-002#2
Closes#9
Copied from the base with identity-only edits: the docstrings name days 20 and 21, and the package main page describes the whole game. The values are unchanged; MIL-003 checks them against the day-21 lectures.
Task: MIL-001#3
Closes#3
