用python turtle库画一个立体的黄色五层书架

好的，以下是解决方案：

import turtle

# 设置画笔颜色和填充颜色为黄色
turtle.color("yellow")
turtle.begin_fill()

# 画第一层
turtle.forward(120)
turtle.left(90)
turtle.forward(30)
turtle.left(90)
turtle.forward(120)
turtle.left(90)
turtle.forward(30)

# 画第二层
turtle.up()
turtle.goto(0, 30)
turtle.down()
turtle.forward(120)
turtle.left(90)
turtle.forward(30)
turtle.left(90)
turtle.forward(120)
turtle.left(90)
turtle.forward(30)

# 画第三层
turtle.up()
turtle.goto(0, 60)
turtle.down()
turtle.forward(120)
turtle.left(90)
turtle.forward(30)
turtle.left(90)
turtle.forward(120)
turtle.left(90)
turtle.forward(30)

# 画第四层
turtle.up()
turtle.goto(0, 90)
turtle.down()
turtle.forward(120)
turtle.left(90)
turtle.forward(30)
turtle.left(90)
turtle.forward(120)
turtle.left(90)
turtle.forward(30)

# 画第五层
turtle.up()
turtle.goto(0, 120)
turtle.down()
turtle.forward(120)
turtle.left(90)
turtle.forward(30)
turtle.left(90)
turtle.forward(120)
turtle.left(90)
turtle.forward(30)

# 填充颜色
turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 等待用户关闭窗口
turtle.done()

运行以上代码，将会弹出一个窗口，显示一个立体的黄色五层书架。
