Questions tagged [zope.interface]

The zope.interface module provides an implementation of "object interfaces" for Python.

Interfaces are a mechanism for labeling objects as conforming to a given API or contract. The zope.interface package can be considered as an implementation of the Design By Contract methodology in Python.

zope.interface does not depend on the Zope server framework and does not imply using any other part of Zope.
