Making a (Python) Web App is easy!
summary
Builds a working QR‑code generator and a richer Semantic Emoji search, implemented three ways: six lines in Streamlit (very simple but limited layout), more verbose Dash with explicit layout and callbacks (based on Flask+React, now allows duplicate outputs), and Shiny for Python with explicit input/output bindings; QR app uses the segno library to generate images and is deployed (Shiny server, shinyapps.io, Streamlit Community Cloud; Dash needs a WSGI/Heroku path). Streamlit reruns the script on every interaction; Dash/ Shiny give finer control.
