Source code
From turtle import *
From random import randrange
From freegames import square, vector
Food = vector (0,0)
Snake = [vector (10,0)]
Aim = vector (0,-10)
Def change (x, y):
"Change snake direction."
Aim.x = x
Aim.y = y
Def inside (head):
"Return True if head inside boundaries."
Return-200 < head.x < 190 and-200 < head.y < 190
Def move ():
"Move snake forward one segment."
Head = snake [- 1] .copy ()
Head.move (aim)
If not inside (head) or head in snake:
Square (head.x, head.y, 9, 'red')
Update ()
Return
Snake.append (head)
If head = = food:
Print ('Snake:', len (snake))
Food.x = randrange (- 15,15) * 10
Food.y = randrange (- 15,15) * 10
Else:
Snake.pop (0)

For body in snake:
Square (body.x, body.y, 9, 'black')
Square (food.x, food.y, 9, 'green')

Copy the above code to a file with the suffix py and name it snake.py.
Open the console in the directory where the file is located: run pip install freegames, then run python snake.py
