The piecemeal approach to Python is similar to the Clojure way, effectively frameworkless. Use what is needed and assemble it.
Contrast to Django which is a batteries included framework, popular components are:
- Flask: HTTP Serving, routing and serialization.
- Jinja2: Templates, also used by Django.
- WTForms: HTML Forms, definition and rendering.
- SQLAlchemy: Database model.
