When it comes to Python web development, frameworks are the backbone that make your life easier. A framework provides pre-written code, libraries, and patterns so you don’t have to reinvent the wheel every time you build a Python website. Among the many options, two stand out for beginners:

1. Flask – Lightweight and Flexible

Perfect for: Small projects, APIs, and learning web basics.

Features:

Minimalist core – only what you need to get started.
Beginner-friendly and easy to set up.
Great for understanding routing, templates, and HTTP requests.


from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, World! This is my first Python website."

if __name__ == "__main__":
    app.run(debug=True)

Success! With just a few lines of Python coding, you can create a running web server using Flask. It’s the perfect way to learn Python programming for the web.

2. Django – Powerful and Full-Stack

Perfect for: Building complete, production-ready websites and admin dashboards.

Authentication and security tools out-of-the-box.
Highly scalable, great for enterprise-level projects.


# Create a new Django project
django-admin startproject mysite

# Navigate into project
cd mysite

# Run development server
python manage.py runserver

Warning! Django has a steeper learning curve than Flask, but it pays off if you want to build large, feature-rich applications.

Both Flask and Django are amazing. If your goal is to learn Python while understanding how the web works, start with Flask. Once you feel confident, explore Django to unlock advanced Python programming possibilities for the web.

📁 Basic Concepts You’ll Learn in Python Web Development

Before diving deep into projects, it’s important to understand the core concepts that power every Python website. These concepts are the building blocks of modern web development, no matter which framework you use.

Routing – This is how your application decides which URL points to which function (called a view). For example, /about might show your About page.
Views & Templates – The Python code (logic) lives in views, while the design (HTML/CSS) lives in templates. This separation makes websites easier to maintain.
Forms & Requests – Websites aren’t static. You’ll learn to handle user input, like contact forms or login pages, and process the data safely.
Database Integration – Storing and retrieving data using databases such as SQLite, PostgreSQL, or MySQL. This is what powers blogs, e-commerce stores, and social media apps.
Authentication – Adding login, logout, and signup functionality to secure your Python website. Django makes this easy, while Flask allows full customization.

Info! These concepts may sound technical now, but once you build your first small project, they’ll make perfect sense. Each one is an essential step in becoming a professional Python web developer.

Learning these fundamentals step by step will give you a solid foundation not just for Python programming but also for understanding the bigger world of software development.

Create a project file

Make a new folder called myapp and inside it create a file named app.py.

Write your first route


from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, World! Welcome to my first Python website."

if __name__ == "__main__":
    app.run(debug=True)

Run the app
```
python app.py
```
Now open your browser and go to http://127.0.0.1:5000/. 🎉 You just created your first working web app!
