4-7 [화성땅 공동구매] - 뼈대 준비하기

강의자료에서 제공된 코드스니펫을 그대로 복붙하고 돌렸는데 아래와 같은 에러가 뜹니다ㅠㅠ

그대로 복사하여 붙였는데 에러 이유를 모르겠습니다.

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

  • dump() shows all variables in the frame
  • dump(obj) dumps all that's known about the object

Brought to you by DON'T PANIC, your friendly Werkzeug powered traceback interpreter.
