in this tutorial, we will explore building a web gui (graphical user interface) using flask, a lightweight web framework for python. flask is known for its simplicity and ease of use, making it an excellent choice for developing web applications.
before we begin, make sure you have python installed on your machine. you can download it from python.org. additionally, we will use pip to install flask, so make sure it's installed as well.
let's start by creating a basic flask application. create a new file, for example, app.py, and add the following code:
this minimal flask app defines a route for the root url ('/') and renders an html template named index.html.
next, create a folder named templates in the same directory as your app.py. inside this folder, create index.html:
this html file is a simple template that displays a welcome message.
now, go back to your terminal and run the flask app:
visit http://127.0.0.1:5000/ in your web browser, and you should see the welcome message.
let's enhance our web gui by adding a form. update index.html as follows:
in this updated html, we added a simple form that takes the user's name as input.
now, let's update our app.py to handle the form submission:
this modification adds a new route /submit that handles form submissions.
congratulations! you've built a simple python web gui using flask. this tutorial covers the basics, and you can expand on it by adding more features, styling, and functionality to meet your specific requirements. flask's flexibility allows you to create powerful web applications with ease.
