Source Code: snake.py

import random
import curses

def play_game():
    s = curses.initscr()
    curses.curs_set(0)
    sh, sw = s.getmaxyx()
    w = curses.newwin(sh, sw, 0, 0)
    w.keypad(1)
    w.timeout(100)

    snk_x = sw/4
    snk_y = sh/2
    snake = [
        [snk_y, snk_x],
        [snk_y, snk_x-1],
        [snk_y, snk_x-2]
    ]

    food = [sh/2, sw/2]
    w.addch(int(food[0]), int(food[1]), curses.ACS_PI)

    key = curses.KEY_RIGHT

    while True:
        next_key = w.getch()
        key = key if next_key == -1 else next_key

        if snake[0][0] in [0, sh] or snake[0][1] in [0, sw] or snake[0] in snake[1:]:
            curses.endwin()
            quit()

        new_head = [snake[0][0], snake[0][1]]

        if key == curses.KEY_DOWN:
            new_head[0] += 1
        if key == curses.KEY_UP:
            new_head[0] -= 1
        if key == curses.KEY_LEFT:
            new_head[1] -= 1
        if key == curses.KEY_RIGHT:
            new_head[1] += 1

        snake.insert(0, new_head)

        if snake[0] == food:
            food = None
            while food is None:
                nf = [
                    random.randint(1, sh-1),
                    random.randint(1, sw-1)
                ]
                food = nf if nf not in snake else None
            w.addch(food[0], food[1], curses.ACS_PI)
        else:
            tail = snake.pop()
            w.addch(int(tail[0]), int(tail[1]), ' ')

        w.addch(int(snake[0][0]), int(snake[0][1]), curses.ACS_CKBOARD)

user_input = input("Do you want to play the snake game, type 'yes' or 'no': ").lower()

if user_input == "yes":
    play_game()
else:
    quit()
