Flask 기반의 파이썬 웹 프로그래밍 독자문의

네 말씀하신대로 하나하나만 가지고는 실행이 되지 않죠...

열받습니다..책값이 싼것도 아닌데..

from flask import Flask

app = Flask(__name__)

@app.route('/board/<article_id>') 
@app.route('/board', defaults={'article_id': 3})
def board( article_id):
    print(article_id)
    return article_id

if __name__ == "__main__":
    app.run( host="0.0.0.0", debug=True)
    
    
책 44페이지에 이 소스
실행이 된다고 생각하시나요?
테스트는 해보고 책을 쓰신건가요?

실행하면 아래와 같이 에러가 떨어집니다.
기본적으로 확인은 해보시고 책에 소스를 싣어야 하는게 아닌가요?
이 뿐이 아닙니다..
제대로 동작하는 소스가 찾기가 어려워요..
한번 책 전체 소스를 확인해보시고 오류수정한 소스를 올려 주셔야 하는거 아닌가요..

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
