	brad.shape("turtle")
	brad.speed(15)
	# 循环方形
	for i in range(0,36):
		brad.color("pink")
		draw_triangle(brad)
		brad.color("blue")
		draw_circle(brad)
		brad.color("yellow")
		draw_square(brad)	
		brad.right(10)
	brad.right(90)
	brad.forward(200)
	window.exitonclick()
# 方形画圆
draw_art()
# 添加音乐

步骤

  1. 获取画布turtle.Screen()，设置背景色
  2. 获取画笔 turtle.Turtle()，设置画笔形状颜色速度等
  3. 画出想要的图案
