python terminator_Python Turtle.Terminator甚至在使用exitonclick（）之后

我试着为turtle创建函数，使其非常容易绘制形状，代码如下所示import turtle as t

def square():

tw = t.Screen()

for i in range(4):

t.forward(100)

t.right(90)

tw.exitonclick()

def triangle():

tw = t.Screen()

for i in range(3):

t.forward(100)

t.right(120)

tw.exitonclick()

def star():

tw = t.Screen()

for i in range(5):

t.forward(150)

t.right(144)

tw.exitonclick()

当我在shell中运行这段代码时，有一个问题。。。>>> square()

>>> triangle()

Traceback (most recent call last):

File "", line 1, in

triangle()

File "C:\Users\Manop\Desktop\XENON\turtleg.py", line 11, in triangle

t.forward(100)

File "", line 5, in forward

turtle.Terminator

>>> star()

>>> square()

Traceback (most recent call last):

File "", line 1, in

square()

File "C:\Users\Manop\Desktop\XENON\turtleg.py", line 5, in square

t.forward(100)

File "", line 5, in forward

turtle.Terminator

>>>

无法解决问题，因为我甚至使用了exitonclick()
