pip install django
Enter fullscreen mode Exit fullscreen mode

Create a new Django project:

django-admin startproject myproject
Enter fullscreen mode Exit fullscreen mode

Create a new Django app within the project:

cd myproject
python manage.py startapp myapp
Enter fullscreen mode Exit fullscreen mode

Define the models for the app in myapp/models.py:

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=200)
    author = models.CharField(max_length=200)
    published_date = models.DateField()

    def __str__(self):
        return self.title
Enter fullscreen mode Exit fullscreen mode

Create a database table for the models:

python manage.py makemigrations myapp
python manage.py migrate
Enter fullscreen mode Exit fullscreen mode

Define a view for the app in myapp/views.py:

rom django.shortcuts import render
from .models import Book

def book_list(request):
    books = Book.objects.all()
    return render(request, 'book_list.html', {'books': books})
Enter fullscreen mode Exit fullscreen mode

Define a template for the view in myapp/templates/book_list.html:

{% for book in books %}
    <div>{{ book.title }} by {{ book.author }}</div>
{% endfor %}
Enter fullscreen mode Exit fullscreen mode

Define a URL pattern for the view in myapp/urls.py:

rom django.urls import path
from .views import book_list

urlpatterns = [
    path('books/', book_list, name='book_list'),
]
Enter fullscreen mode Exit fullscreen mode

@app.route('/')
def hello_world():
    return 'Hello, World!'
Enter fullscreen mode Exit fullscreen mode

Run the application:

if __name__ == '__main__':
    app.run()
Enter fullscreen mode Exit fullscreen mode

Finally, run the development server:

python app.py
Enter fullscreen mode Exit fullscreen mode

This will start a development server that listens for requests on http://localhost:5000. If you visit that URL in your web browser, you should see the message "Hello, World!" displayed on the page.

from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response

def hello_world(request):
    return Response('Hello, World!')

if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('hello', '/')
        config.add_view(hello_world, route_name='hello')
        app = config.make_wsgi_app()
    server = make_server('localhost', 8080, app)
    server.serve_forever()
