python图形工具turtle绘制国际象棋棋盘

本文实例为大家分享了python图形工具turtle绘制国际象棋棋盘的具体代码，供大家参考，具体内容如下

#编写程序绘制一个国际象棋的棋盘
import turtle
turtle.speed(30)
turtle.penup()
off = true
for y in range(-40, 30 + 1, 10):
 for x in range(-40, 30 + 1, 10):
 if off:
 turtle.goto(x, y)
 turtle.pendown()
 turtle.begin_fill()
 turtle.color("black")
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.end_fill()
 turtle.penup()
 else:
 turtle.goto(x, y)
 turtle.pendown()
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.penup()
 off = bool(int(off) - 1)
 off = bool(int(off) - 1)
turtle.hideturtle()
turtle.done()

通过函数的重用优化代码：

先建立一个usefulturtlefunctions.py 的文件夹

import turtle
#draw a square
def drawsquare():
 turtle.pendown()
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.forward(10)
 turtle.left(90)
 turtle.penup()

再在test中调用它

#编写程序绘制一个国际象棋的棋盘
 
import turtle
from usefulturtlefunctions import *
turtle.speed(30)
turtle.penup()
off = true
for y in range(-40, 30 + 1, 10):
 for x in range(-40, 30 + 1, 10):
 if off:
 turtle.goto(x, y)
 turtle.begin_fill()
 turtle.color("black")
 drawsquare()
 turtle.end_fill()
 turtle.penup()
 else:
 turtle.goto(x, y)
 drawsquare()
 off = bool(int(off) - 1)
 off = bool(int(off) - 1)
turtle.hideturtle()
turtle.done()

最后结果：
