用Python画名字，用turyle库

名字白璐璐，请帮忙算坐标，谢谢
import turtle

def run(angle, lenth):
turtle.seth(angle)
turtle.fd(lenth)

def change(x, y):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
def init():
turtle.pensize(10)
turtle.pencolor("purple")

turtle.setup(800, 400, 200, 200)
init()

写字直接用write就行了，如下：

import turtle
t= turtle.Turtle()
t.write("霜叶红于二月花", font=("微软雅黑", 20, "normal")) #fonttype有normal, bold, italic, underline
turtle.mainloop()
