1) 장고디렉터리의 구조

django가 실행되면 맨처음은 최초생성된 장고 디렉터리를 바라보게 되어있어요.
제가 만든 django 디렉터리명은 "mynewjangodirec"입니다.
django 서버가 시작되면 mynewjangodirec 디렉터리 하단의 settings.py와 urls.py를 맨처음 참고합니다!

3) 생성된장고디렉터리 하단의 settings.py 살펴보기

장고에서 사용되는 APP은 지금보는 settings.py 파일의 "INSTALLED_APPS"라는 리스트 안에 명시되어야 합니다.

그래야 장고에서 해당 APP을 인식하여 쓸 수 있어요.
