Как насчет синего фона в сочетании с с печатью зеленая трава:
from turtle import Screen, Turtle
WIDTH, HEIGHT = 700, 390
CURSOR_SIZE = 20
screen = Screen()
screen.setup(WIDTH, HEIGHT)
screen.bgcolor('blue')
background = Turtle('square', visible=False)
background.shapesize(HEIGHT/2 / CURSOR_SIZE, WIDTH / CURSOR_SIZE)
background.penup()
background.sety(-HEIGHT/4)
background.color('green')
background.stamp()
# your code here
screen.mainloop()
Или, если вы предпочитаете нарисованный газон:
from turtle import Screen, Turtle
WIDTH, HEIGHT = 700, 390
screen = Screen()
screen.setup(WIDTH, HEIGHT)
screen.bgcolor('blue')
background = Turtle(visible=False)
background.penup()
background.setx(-WIDTH/2)
background.pendown()
background.color('green')
background.begin_fill()
for _ in range(2):
background.forward(WIDTH)
background.right(90)
background.forward(HEIGHT/2)
background.right(90)
background.end_fill()
# your code here
screen.mainloop()
