Build a Gradio app with interactive tabs for ‘Hello’ and ‘Bye,’ dynamically displaying random greetings and farewells using Python’s random module for added fun. This code demonstrates the use of Gradio’s Blocks and TabbedInterface for creating intuitive web-based user interfaces.

tabbed.py

import gradio as gr
import random

def create_hello_world_tab():
    with gr.Blocks() as hello_world:
        def greet_on_load():
            return f"Random Hello Number: {random.randint(1, 100)}"
        
        output = gr.Textbox(label="Greeting Message")
        
        gr.Interface(
            fn=lambda name: "Hello " + name,
            inputs="text",
            outputs=output
        )
        
        hello_world.load(greet_on_load, inputs=None, outputs=output)
    return hello_world

def create_bye_world_tab():
    with gr.Blocks() as bye_world:
        def bye_on_load():
            return f"Random Bye Number: {random.randint(101, 200)}"
        
        output = gr.Textbox(label="Farewell Message")
        
        gr.Interface(
            fn=lambda name: "Bye " + name,
            inputs="text",
            outputs=output
        )
        
        bye_world.load(bye_on_load, inputs=None, outputs=output)
    return bye_world


hello_world = create_hello_world_tab()
bye_world = create_bye_world_tab()

with gr.Blocks() as demo:
    gr.TabbedInterface(
        [hello_world, bye_world], 
        ["Hello World", "Bye World"]
    )
