b. To create a new project

1. To create a new project
  django-admin startproject projectname
2. Project Structure
    projectname/
        manage.py
        projectname/
            __init__.py
            settings.py
            urls.py
            asgi.py
            wsgi.py

These files are:
    - The outer projectname/ root directory is a container for your project. Its name doesn’t matter to Django; you can rename it to anything you like.
    - manage.py: A command-line utility that lets you interact with this Django project in various ways. You can read all the details about manage.py in django-admin and manage.py.
      a. To run the server. Migrations comes under this. It helps us to manage the project.
    - The inner mysite/ directory is the actual Python package for your project. Its name is the Python package name you’ll need to use to import anything inside it (e.g. projectname.urls).
    - projectname/__init__.py: An empty file that tells Python that this directory should be considered a Python package.
    - projectname/settings.py: Settings/configuration for this Django project. Django settings will tell you all about how settings work.
    - projectname/urls.py: The URL declarations for this Django project; a “table of contents” of your Django-powered site. You can read more about URLs in URL dispatcher.
    - projectname/asgi.py: An entry-point for ASGI-compatible web servers to serve your project.
    - projectname/wsgi.py: An entry-point for WSGI-compatible web servers to serve your project.
    - projectname: This is also an app given by django default.

c. To run Development Server

  python manage.py runserver

2. To change the port
  python manage.py runserver 4444
  python manage.py runserver port_number
