Flask is a lightweight web application framework for Python that allows you to build web applications quickly and with minimal code. In this tutorial, we'll walk through the process of creating a simple web application using Flask and integrating Python code into HTML templates.
Make sure you have Python installed on your system. You can download it from python.org.
Open a terminal or command prompt and install Flask using the following command:
Create a new directory for your project and navigate into it. Inside the project directory, create a new file named app.py:
This script initializes a Flask application, defines a route for the root URL ('/'), and renders an HTML template named index.html.
Inside the project directory, create a folder named templates. This is where Flask will look for HTML templates. Inside the templates folder, create a file named index.html:
In this HTML template, we've added a basic structure and included a placeholder for content using the {% block content %} and {% endblock %} tags.
Modify the index route in app.py to pass data to the HTML template:
Update the content block in index.html to display the message:
Now, when you run the Flask application (python app.py) and visit http://127.0.0.1:5000/ in your browser, you should see the message "Hello, Flask!" displayed on the webpage.
Congratulations! You've successfully built a simple web application with Flask and integrated Python code into HTML templates. This tutorial provides a foundation for more complex web applications and dynamic content generation. Explore Flask's documentation for more features and possibilities: Flask Documentation.
