        pen.right(10)
    pen.right(90)
    pen.forward(200)

def draw_art():
    pen = turtle.Turtle()
    pen.color("yellow")
    pen.shape("turtle")
    pen.speed(8)
    window = turtle.Screen()
    window.bgcolor("red")   
    draw_h(pen)
    pen.up()
    pen.forward(10)
    draw_j(pen)
    pen.up()
    pen.goto(170,0)
    pen.down()
    draw_y(pen)
    pen.up()
    pen.goto(-100,100)
    pen.down()
    draw_flower(pen)
    window.exitonclick()
draw_art()

import turtle

def draw_circle(angie): 
    angie.circle(50)

def draw_triangle(triangle):
    for y in range(0,3):
        triangle.forward(100)
        triangle.right(120)

def draw_square(turtle):
    for i in range(0,4):
        turtle.forward(100)
        turtle.right(90)

def draw_art():
    window = turtle.Screen()
    window.bgcolor("red")
    brad = turtle.Turtle()
    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
