Django Installation Guide: Detailed tutorials to help you get started easily, specific code examples are required

Introduction:
Django is an open source web framework based on Python. The design purpose is to enable developers to develop high-quality web applications quickly and easily. Installing Django is the first step to using the framework. This article will introduce in detail how to install Django and provide specific code examples to help readers get started easily.

Part One: Preparation
Before we start, we need to prepare some necessary conditions:

1. Install Python: Django is developed based on Python, so first make sure that it is installed on the computer Python is installed on. Visit the Python official website (https://www.python.org/) to download and install the latest version of Python.

2. Check the Python version: Enter the following command in the terminal to check whether the Python version is installed correctly:

   python --version

   If you see the correct version number, Python has been successfully installed.

Part 2: Install Django
Below we will introduce how to use Python's package management tool pip to install Django.

1. Update pip: Enter the following command in the terminal to upgrade pip:

   pip install --upgrade pip

   This command will upgrade pip to the latest version.

2. Install Django: Enter the following command in the terminal to install Django:

   pip install django

   This command will automatically download and install the latest version of Django.

3. Verify installation: Enter the following command in the terminal to verify whether Django is successfully installed:

   django-admin --version

   If you see the version number of Django, Django has been successfully installed.

Part 3: Create a Django project
Next, we will create a new Django project, taking the project named "myproject" as an example.

1. Create a project: Enter the following command in the terminal to create a project:

   django-admin startproject myproject

   This command will create a folder named "myproject" in the current directory. The folder is the Django project directory.

2. Start the development server: Enter the project directory you just created and enter the following command to start the Django development server:

   cd myproject
   python manage.py runserver

   This command will start a web server for development , listening on http://127.0.0.1:8000/ by default.

3. Verify the project: Visit http://127.0.0.1:8000/ in the browser. If you see a "Congratulations!" message, the project has been successfully started.

Part 4: Creating Django Applications
In Django, a project is composed of multiple applications. Next we will create an application called "myapp".

1. Create an application: Enter the following command in the terminal to create an application:

   python manage.py startapp myapp

   This command will create a folder named "myapp" in the project directory. This folder is the application directory.

2. Register an application: Open the settings.py file in the project directory, find the INSTALLED_APPS list, and add 'myapp' to the list.

3. Create a view: Create a file named views.py in the application directory and enter the following code:

   from django.http import HttpResponse
   
   def hello(request):
    return HttpResponse("Hello Django!")

4. Configure URL: Open the project directory urls.py file under, find the urlpatterns list, add the following code:

   from myapp.views import hello
   
   urlpatterns = [
    path('hello/', hello),
   ]

5. Verify the application: Re-run the development server in the terminal, visit http://127.0.0.1:8000/hello/, If you see "Hello Django!" output, the application has been successfully created and configured.
