Flask is a Python micro web framework that allows you to build web applications quickly and with minimal boilerplate code. In this guide, we'll walk you through the process of creating a basic Flask web page. You'll learn how to set up a Flask application, create routes, and render HTML templates to display content.
Step 1: Setting Up Your Flask Application
Before you can create a Flask web page, you need to set up your Flask application. Here's a minimal example:
from flask import Flask
app = Flask(__name)
Step 2: Creating a Route
Create a route that defines the content of your web page. Routes in Flask are functions that are executed when a specific URL is accessed. Here's an example of a route that displays a simple "Hello, World!" message:
return 'Hello, World!'
Step 3: Running Your Flask Application
To run your Flask application, add the following code at the end of your script:
if __name__ == '__main__':
Now, you can run your application with the command
python your_app.py and access your basic Flask web page in a web browser.
Step 4: Accessing Your Flask Web Page
Open a web browser and navigate to
http://localhost:5000/ to view your Flask web page. You'll see the "Hello, World!" message displayed in the browser.
Creating a basic Flask web page is a simple but essential step in web development. You've learned how to set up a Flask application, create a route, and display content on a web page. You can further enhance your web page by adding templates, forms, and more complex routes as your project grows.
