请教Python的turtle中stamp的作用意义是什么，可否举例，表示不明白，谢谢。

如题所述

turtle.stamp()

Stamp a copy of the turtle shape onto the canvas at the current turtle position. Return a stamp_id for that stamp, which can be used to delete it by calling clearstamp(stamp_id).

>>> turtle.color("blue")>>> turtle.stamp()11>>> turtle.fd(50)


turtle.clearstamp(stampid)

Parameters:

stampid – an integer, must be return value of previous stamp() call    

Delete stamp with given stampid.

>>> turtle.position()(150.00,-0.00)>>> turtle.color("blue")>>> astamp = turtle.stamp()>>> turtle.fd(50)>>> turtle.position()(200.00,-0.00)>>> turtle.clearstamp(astamp)>>> turtle.position()(200.00,-0.00)


turtle.clearstamps(n=None)
