python - 为什么 Python IDE 即使安装正确也会显示这样的错误

Question

1. 它显示如turtle.Terminator
2. AttributeError：模块 'turtle' 没有属性 'forward'

>>> import turtle
>>> for i in range(50,100,10):
...     for j in range(4):
...             turtle.forward(i)
...             turtle.left(90)
...
Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
  File "<string>", line 5, in forward
turtle.Terminator

注意：我的例外结果是 4 平方
