Django - The Web framework for perfectionists with deadlines
Django ist ein in Python geschriebenes Open-Source-Webanwendungs-Framework, das eine schnelle Entwicklung und wiederverwendbare Anwendungen ermöglicht. Es basiert auf den Prinzipien der Losen Kopplung und des DRY (Don't Repeat Yourself) und wird von einer großen, freundlichen Community unterstützt. Der Vortrag von Markus Zapke-Gründemann bei Webmontag Leipzig bietet eine Übersicht über Django, seine Struktur, Funktionen und die lokale Entwicklergemeinschaft.
