Dieses Dokument beschreibt die Python Enhancement Proposals (PEPs). Diese
dienen der Diskussion und Dokumentation des Python-Entwicklungsvorgangs und der
Python-Nutzung. Jeder PEP hat eine NUMMER (die sich nicht mehr ändert, sobald
sie vergeben wurde) und einen TITEL, eine KATEGORIE, einen TYP und einen STATUS
sowie den BESCHREIBUNGSTEXT.
