Avaiga/taipy ? reverse-engineered prompt

Build me a Python library and web app toolkit that helps data people turn their models and datasets into real web apps fast.

I want something where a user can plug in a data pipeline or ML logic, then get a clean interface for viewing data, changing inputs, running scenarios, and seeing results update on the page. It should also support basic things like user login, roles, scheduled jobs, and connecting to external data sources. Make it feel production ready, not like a demo, with good docs, examples, and a nice starter experience.

Please set it up so it works with current Python versions, includes tests, and is easy to install and run locally. If you need to check current best practices for any libraries or web tooling, look up the latest docs online first.
