关于turtle绘图的问题

左游仙

如下所示：
>>> import turtle
>>> turtle.showturtle()
Traceback (most recent call last):
  File "<pyshell#182>", line 1, in <module>
    turtle.showturtle()
  File "<string>", line 5, in showturtle
turtle.Terminator
>>> turtle.showturtle()
为什么第一遍输入turtle.showturtle()的时候总会报错，再输入一遍就不会报错了

我的刚好相反，输入奇数遍不会报错。

1. >>> turtle.showturtle()
   
2. >>> turtle.showturtle()
   
3. Traceback (most recent call last):
   
4.   File "<pyshell#3>", line 1, in <module>
   
5.     turtle.showturtle()
   
6.   File "<string>", line 5, in showturtle
   
7. turtle.Terminator
   
8. >>> turtle.showturtle()
   
9. >>> turtle.showturtle()
   
10. Traceback (most recent call last):
    
11.   File "<pyshell#5>", line 1, in <module>
    
12.     turtle.showturtle()
    
13.   File "<string>", line 5, in showturtle
    
14. turtle.Terminator
    
15. >>> turtle.showturtle()

是不是你前面实例化过 Turtle()？
