Python画一个象棋棋盘

可以使用Python的turtle库来画一个象棋棋盘，代码如下：

import turtle

# 设置棋盘大小
board_size = 400

# 设置格子大小
grid_size = board_size // 9

# 初始化画笔
pen = turtle.Turtle()
pen.speed()
pen.hideturtle()

# 画棋盘边框
pen.penup()
pen.goto(-board_size // 2, board_size // 2)
pen.pendown()
pen.goto(board_size // 2, board_size // 2)
pen.goto(board_size // 2, -board_size // 2)
pen.goto(-board_size // 2, -board_size // 2)
pen.goto(-board_size // 2, board_size // 2)

# 画横线
for i in range(8):
    pen.penup()
    pen.goto(-board_size // 2, board_size // 2 - grid_size * (i + 1))
    pen.pendown()
    pen.goto(board_size // 2, board_size // 2 - grid_size * (i + 1))

# 画竖线
for i in range(8):
    pen.penup()
    pen.goto(-board_size // 2 + grid_size * (i + 1), board_size // 2)
    pen.pendown()
    pen.goto(-board_size // 2 + grid_size * (i + 1), -board_size // 2)

# 画九宫格
pen.penup()
pen.goto(-board_size // 2 + grid_size * 3, board_size // 2)
pen.pendown()
pen.goto(-board_size // 2 + grid_size * 5, board_size // 2)
pen.goto(-board_size // 2 + grid_size * 5, board_size // 2 - grid_size * 2)
pen.goto(-board_size // 2 + grid_size * 3, board_size // 2 - grid_size * 2)
pen.goto(-board_size // 2 + grid_size * 3, board_size // 2)

pen.penup()
pen.goto(-board_size // 2 + grid_size * 3, -board_size // 2 + grid_size * 2)
pen.pendown()
pen.goto(-board_size // 2 + grid_size * 5, -board_size // 2 + grid_size * 2)
pen.goto(-board_size // 2 + grid_size * 5, -board_size // 2)
pen.goto(-board_size // 2 + grid_size * 3, -board_size // 2)
pen.goto(-board_size // 2 + grid_size * 3, -board_size // 2 + grid_size * 2)

# 画楚河汉界
pen.penup()
pen.goto(-board_size // 2 + grid_size * 3, board_size // 2 - grid_size * 4)
pen.pendown()
pen.goto(-board_size // 2 + grid_size * 5, board_size // 2 - grid_size * 6)

pen.penup()
pen.goto(-board_size // 2 + grid_size * 5, board_size // 2 - grid_size * 4)
pen.pendown()
pen.goto(-board_size // 2 + grid_size * 3, board_size // 2 - grid_size * 6)

# 隐藏画笔
pen.hideturtle()

# 等待用户关闭窗口
turtle.done()

运行以上代码，即可在窗口中看到一个完整的象棋棋盘。
