FastHTML

fasthtml is the Python web UI framework used in the Section 3 dashboard scaffold in Brevvie Python + AI — Section 3: Data, Polars & Pair Programming. It is presented as a lightweight way to generate interactive pages directly from Python.

Role in the source

• builds the dashboard page structure in Python
• serves HTML without requiring a heavy frontend framework
• pairs naturally with htmx for interactive updates

Why it matters

The lesson uses FastHTML to show that a small internal dashboard can be built with simple Python-first tools rather than a large JavaScript stack.
