Are you interested in learning how to create your own web applications but feel overwhelmed by the complexity of programming? You're not alone! Many beginners find the world of web development daunting—especially when it comes to choosing the right framework. Django, a powerful web framework built on Python, simplifies the development process without sacrificing functionality. In this tutorial, we'll guide you through setting up Django and taking those first exciting steps toward building your very own web app. Whether you're a complete novice or have some programming experience, this post is designed for you to gain the confidence and skills needed to start your journey in web development with Python!

What is Django?​

Django is a free and open-source web framework that helps developers create web applications quickly and efficiently. It follows the Model-View-Template (MVT) architectural pattern, which encourages clean and pragmatic design. Here's why you should consider using Django:

  • Rapid Development: Django allows you to develop web applications in a fraction of the time.
  • Scalability: It’s flexible enough to handle complex applications.
  • Security: Protects against common security threats.

Setting Up Django​

Now that you know what Django is, let’s get started with setting it up.

Step 1: Installing Python​

Django runs on Python, so you need to have Python installed on your system. You can download Python from the official website. Choose the version that corresponds to your operating system.

Step 2: Installing Django​

Once Python is installed, you can install Django using pip, Python’s package manager. Open your command line or terminal and run:

pip install django

Step 3: Creating Your First Project​

To create a new Django project, you can use the following command:

django-admin startproject myproject

This command creates a new directory named myproject with the basic structure of a Django application.

Step 4: Running the Development Server​

Navigate into your project directory and run the following command to start the development server:

cd myproject
django-admin runserver

Now, you can see your web application in your browser by visiting http://127.0.0.1:8000.

Building a Web App​

With your project set up, it's time to build your first web app! We'll create a simple app called hello.

Step 1: Create Your App​

Inside your project directory, run:

django-admin startapp hello

This creates a new application folder named hello.

Step 2: Views and URLs​

Open hello/views.py and define a simple view:

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, World!")

Next, set up a URL mapping by creating a file called urls.py inside the hello directory:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='index'),
]

Step 3: Connect the App to the Project​

Edit myproject/urls.py to include your app's URLs:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('admin/', admin.site.urls),
    path('hello/', include('hello.urls')),
]

Now if you visit http://127.0.0.1:8000/hello/, you should see the message "Hello, World!" on your screen.

Next Steps​

Congratulations! You've just created your first Django web app. To further your learning:
