Title: Getting Started with Python Web Frameworks: A Comprehensive Tutorial
Introduction:
Python is a versatile programming language, and when it comes to web development, there are several powerful frameworks to choose from. In this tutorial, we will explore three popular Python web frameworks: Flask, Django, and FastAPI. We'll cover the basics, including installation, project structure, routing, templates, and database integration.
Create a file named app.py and add the following code:
Run the app using:
Visit http://localhost:5000 in your browser to see the "Hello, World!" message.
Visit http://localhost:8000 in your browser to see the Django welcome page.
Define a simple view in myapp/views.py:
Add the view to myproject/urls.py:
Visit http://localhost:8000/hello in your browser to see the "Hello, Django!" message.
Create a file named main.py and add the following code:
Run the app using:
Visit http://localhost:8000 in your browser to see the FastAPI welcome page.
Explore each framework's documentation to learn more about advanced features like middleware, authentication, and database integration. Additionally, consider using tools like SQLAlchemy or Django ORM for database interactions.
Remember, the choice of framework depends on your project requirements, and each of these frameworks excels in different areas. Happy coding!
