用turtle库画一个黄色的wjn

好的，可以参考以下代码绘制一个黄色的“wjn”：

import turtle

# 设置画笔
pen = turtle.Pen()
pen.pensize(5)
pen.speed(5)

# 设置画笔颜色为黄色
pen.color("yellow")

# 画"W"
pen.left(90)
pen.forward(100)
pen.right(135)
pen.forward(50)
pen.left(90)
pen.forward(50)
pen.right(135)
pen.forward(100)

# 移动到下一个字母的起始位置
pen.penup()
pen.left(90)
pen.forward(50)
pen.right(90)
pen.forward(20)
pen.pendown()

# 画"J"
pen.circle(30, 180)
pen.right(90)
pen.forward(60)

# 移动到下一个字母的起始位置
pen.penup()
pen.right(90)
pen.forward(20)
pen.left(90)
pen.forward(100)
pen.left(90)
pen.forward(20)
pen.pendown()

# 画"N"
pen.left(90)
pen.forward(100)
pen.right(145)
pen.forward(110)
pen.left(145)
pen.forward(100)

# 隐藏画笔
pen.hideturtle()

turtle.done()

运行上面的代码，就可以得到一个黄色的由"W"、"J"、"N"三个字母组成的图形。
