turtle 模块以面向对象和面向过程的方式提供 turtle 图形基元。由于它使用tkinter作为基础图形,因此需要安装有Tk支持的Python版本。
turtle .clear()
此函数用于从屏幕上删除海龟的图形。不要移动 turtle 的状态和位置,其他 turtle 的图纸也不受影响。不需要任何参数。
用法:turtle.clear()
参数:None
Returns:Nothing
下面是上述方法的实现和一些示例:
范例1:
# import package
import turtle
# motion
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
# clear the drawing
# and remain turtle
# as it is
turtle.clear()
输出:
范例2:
# import package
import turtle
# make a turtle object
# and do some drawing
t1 = turtle.Turtle()
t1.up()
t1.setpos(-100, 50)
t1.down()
t1.circle(50)
# make a turtle object
# and do some drawing
t2 = turtle.Turtle()
t2.up()
t2.setpos(50, 50)
t2.down()
t2.circle(50)
# make a turtle object
# and do some drawing
t3 = turtle.Turtle()
t3.up()
t3.setpos(50, -100)
t3.down()
t3.circle(50)
# make a turtle object
# and do some drawing
t4 = turtle.Turtle()
t4.up()
t4.setpos(-100, -100)
t4.down()
t4.circle(50)
# here we clear the work done by turtle
# objects:t1 and t3 only but turtle
# shape remain as it is
t1.clear()
