Tutorial: Integrating Python with HTML
In this tutorial, we'll explore how to integrate Python with HTML to create dynamic web pages. We'll use Python's Flask framework, which is a lightweight WSGI web application framework. Flask allows us to easily build web applications with Python.
Step 1: Setting up Flask
First, make sure you have Python installed on your system. You can download it from python.org. Once Python is installed, you can install Flask using pip, Python's package manager.
Step 2: Creating a Flask Application
Create a new directory for your project and navigate into it. Inside this directory, create a new Python script. Let's call it app.py.
This script creates a simple Flask application with a single route (/) that returns "Hello, World!" when accessed.
Step 3: Running the Flask Application
To run your Flask application, execute the following command in your terminal:
This will start a development server, and you can visit http://127.0.0.1:5000 in your web browser to see your application in action.
Step 4: Integrating HTML with Python
Now, let's integrate HTML with Python. We'll create a template file using Jinja2, a modern and designer-friendly templating language for Python. Create a new directory called templates in your project directory. Inside the templates directory, create a new file called index.html.
In this HTML file, we're using a placeholder {{ name }} which will be replaced with dynamic content from our Python code.
Step 5: Passing Data to the HTML Template
Modify the index route in app.py to render the HTML template with dynamic content.
In this updated code, we're passing a variable name to the render_template function, which will be accessible in the HTML template.
Step 6: Running the Application Again
Run your Flask application again using python app.py, and visit http://127.0.0.1:5000 in your browser. You should see "Hello, John!" displayed on the webpage.
Congratulations! You've successfully integrated Python with HTML using Flask. You can now build more complex web applications by combining Python's powerful backend capabilities with HTML's flexible frontend design.
