This beginner tutorial introduces Gradio as a Python library for turning functions into browser interfaces. The examples run on the presenter's own system through a local web server. They demonstrate interface building with ordinary Python logic rather than model inference.
Setup starts with a project folder and virtual environment in Visual Studio Code. The presenter recommends Python 3.10 or above, demonstrates environment activation on Windows, and notes that macOS and Linux use a different command. After installing Gradio with pip, the tutorial checks the installed version and creates app.py.
The first app connects a greeting function to text input and output through gr.Interface. Calling demo.launch() starts the app and provides a local browser URL. The presenter then adds a title, description and clickable examples.
A second app counts words, characters and sentences. It uses text.split() for words and a simple punctuation-based sentence count, so the example should not be read as a demonstration of robust linguistic analysis. A five-line gr.Textbox, placeholder text and output labels make the form easier to use.
The final section adds share=True to launch() to create a temporary public link alongside the local address. The presenter treats this as a way to show a demo and recommends considering proper hosting for a serious project.
