Turtle是Python中的一个内建模块。它提供了使用屏幕（纸板）和Turtle（笔）的绘画。为了在屏幕上画东西，我们需要移动Turtle（笔）。为了移动Turtle，有一些函数，如forward()、backward()等。
绘制棋盘的步骤如下：
导入Turtle并制作一个物体。设置屏幕尺寸和Turtle位置。定义一个方法来画一个正方形在另一个循环下调用该方法8次，以替代颜色进行8次。隐藏Turtle对象。以下是实现。
# import turtle packageimport turtle # create screen objectsc = turtle.Screen() # create turtle objectpen = turtle.Turtle() # method to draw squaredef draw(): for i in range(4): pen.forward(30) pen.left(90) pen.forward(30) # Driver Codeif __name__ == "__main__" : # set screen sc.setup(600, 600) # set turtle object speed pen.speed(100) # loops for board for i in range(8): # not ready to draw pen.up() # set position for every row pen.setpos(0, 30 * i) # ready to draw pen.down() # row for j in range(8): # conditions for alternative color if (i + j)% 2 == 0: col ='black' else: col ='white' # fill with given color pen.fillcolor(col) # start filling with colour pen.begin_fill() # call method draw() # stop filling pen.end_fill() # hide the turtle pen.hideturtle() # This code is contributed by Deepanshu Rustagi.输出 :
