interface
¶
interface
is a library for declaring interfaces and for statically
asserting that classes implement those interfaces. It provides stricter
semantics than Python’s built-in abc
module, and it aims to produce
exceptionally useful error messages when interfaces aren’t satisfied.
interface
supports Python 2.7 and Python 3.4+.
Quick Start¶
from interface import implements, Interface
class MyInterface(Interface):
def method1(self, x):
pass
def method2(self, x, y):
pass
class MyClass(implements(MyInterface)):
def method1(self, x):
return x * 2
def method2(self, x, y):
return x + y
