Your task is to write a program that will read in an environment, a start state and a goal state, and conduct a search to find a path between start and goal. You may implement any of the search algorithms discussed in lectures. Your output should be in the form of a space-separated...

python3 manage.py startapp hello 此命令會建立一個名為hello的資料夾,其中包含多個程式碼檔案和一個子資料夾。 其中,您經常會使用views.py(包含定義 Web 應用程式中頁面的函式) 和models.py(包含定義資料物件的類別)。 Django 的系統管理公用程式會使用migrations資料夾來管理資料庫版本,如本教學課程稍後所討論。
