Python画国际象棋盘

自己写的方法

import turtle as t
def square(n):#画一个正方形，pendown和penup可选择是否显示路径
    for i in range(4):
        t.pendown()
        t.fd(n)
        t.left(90)
        t.penup()

def BTW():#先白后黑
    for i in range(8):
        if i % 2 != 0:
            t.begin_fill()
            square(n)
            t.fd(n * 2)
            t.end_fill()

def WTB(): #先黑后白
    for i in range(8):
        if i % 2 == 0:
            t.begin_fill()
            square(n)
            t.fd(n * 2)
            t.end_fill()

n = eval(input()) #小方块的边长由用户决定
#t.setup(600,600)    #设置窗口大小
t.speed(30) #海龟移动速度
t.penup()
t.color("black")
j=-4
for i in range(4):
    t.goto(-4*n, j * n)
    j += 1
    BTW()
    t.goto(-3*n,j * n)
    WTB()
    j += 1
t.goto(-4*n,-4*n)
t.pendown()
square(8*n)
t.hideturtle()#t.ht()
t.done()
