Python中的turtle.clearstamp()方法

turtle模块以面向对象和面向过程的方式提供Turtle图形基元。因为它使用 Tkinter 作为底层图形，它需要安装一个支持 Tk 的 Python 版本。

turtle.clearstamp()

turtle.clearstamp()方法用于删除turtle的全部或前/后n个邮票。这个方法需要一个整数的参数。所以，用一个id做的印章会被它清除掉。

语法: turtle.clearstamp(stampid)

参数:

stampid – 一个整数，必须是之前调用stamp()的返回值。

下面是上述方法的实现和一些例子。

例子1 :

# import package
import turtle
  
  
# set turtle speed to slowest
# for better understandings
turtle.speed(1)
  
# motion with stamps
# and their ids
turtle.forward(50)
id1 = turtle.stamp()
  
turtle.forward(50)
id2 = turtle.stamp()
  
turtle.forward(50)
id3 = turtle.stamp()
  
# hide the turtle to
# clarify stamps
turtle.ht()
  
# clear the stamps
# of id : id1 and id3
turtle.clearstamp(id1)
turtle.clearstamp(id3)

输出 :

例子2 :

# import package
import turtle 
  
# list to store ids
ids = []
  
# loop to create motion
# with stamps
for i in range(12):
      
    # motion
    turtle.forward(50)
      
    # stampid
    id = turtle.stamp()
    lst.append(id)
    turtle.right(30)
  
# hide the turtle for 
# better understandings
turtle.ht()
  
# loop for clear stamps with 
# their ids using clearstamp
# half stamps are cleared
for i in range(len(lst)//2):
    turtle.clearstamp(lst[i])
