Fun Fact Generator Web App in Python

Last Updated : 23 Feb, 2026

In this tutorial, we will create a Fun Fact Generator Web App in Python using the PyWebIO module. This app fetches random fun facts from the Useless Facts API and displays them on a web interface.

PyWebIO is a Python library that allows you to build simple web applications or browser-based GUI apps without writing HTML or JS. It provides:

  • Functions for input and output in the browser
  • Easy styling for text and buttons
  • Session handling for interactive applications

You can install it using:

pip install pywebio

How the App Works

  1. Fetch data: The app sends a GET request to the Useless Facts API.
  2. Parse JSON: The response is parsed using the json module to extract the fact text.
  3. Display fact: The fact is displayed on the web interface using PyWebIO's put_text and style.
  4. Interactive button: A "Click me" button allows users to generate new facts without refreshing the page.

    put_html(

        '<h2><img src="https://media.geeksforgeeks.org/wp-content/uploads/20210720224119/MessagingHappyicon.png" width="7%"> Fun Fact Generator</h2>'
        '</p>'
    )
    
    url = "https://uselessfacts.jsph.pl/random.json?language=en"
    
    response = requests.get(url)
    data = json.loads(response.text)
    
    useless_fact = data['text']
    style(put_text(useless_fact), 'color:blue; font-size: 30px')
    
    put_buttons(
        [dict(label='Click me', value='outline-success', color='outline-success')],
        onclick=get_fun_fact
    )

if __name__ == '__main__':
    put_html(
        '<p align="left">'
        '<h2><img src="https://media.geeksforgeeks.org/wp-content/uploads/20210720224119/MessagingHappyicon.png" width="7%"> Fun Fact Generator</h2>'
        '</p>'
    )
    
    put_buttons(
        [dict(label='Click me', value='outline-success', color='outline-success')],
        onclick=get_fun_fact
    )
    
    hold()
