海龟绘图（turtle）

1.绘制正方形

import turtle as t
t.reset()
t.color('red')
i=200
t.speed=0
while i!=0:
    t.forward(i)
    t.left(90)
    i=i-5
    t.forward(i)
    t.left(90)
    t.forward(i)
    t.left(90)
    i=i-5
    t.forward(i)
    t.left(90)

2.绘制象棋棋盘，完成了一半

    turtle.penup()
    turtle.goto(start,end+i*40)
    turtle.pendown()
    turtle.goto(start2,end2+i*40)
