    raise UnexpectedTypeException
NameError: name 'UnexpectedTypeException' is not defined

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "tests.py", line 20, in <module>
    except UnexpectedTypeException:
NameError: name 'UnexpectedTypeException' is not defined

I think Python test is broken. (I'm tried to raise UnexpectedTypeException and another errors but nothing really worked)

man, you are crazy!

I think this is too difficult for 6kyu, rather closer to 4kyu.
