Python is een objectgeoriënteerde programmeertaal die kan worden gebruikt om eenvoudige tot complexe platformonafhankelijke applicaties te ontwikkelen. De 3.x-serie is niet meer compatibel met de voorgaande versietakken, omdat de Python-ontwikkelaars de taal hebben ontdaan van oude code en enkele aanwezige ontwerpfouten. Enkele dagen geleden is zowel versie 3.1.3 als versie 2.7.1 uitgebracht, voorzien van de volgende lijst met veranderingen:
What's New in Python 3.1.3?
Core and Builtins:Library:
