#coding=utf-8
class Target(object):
    def specific_request(self):
        return 'Hello Adapter Pattern!'

# object adapter
class Adapter(object):
    def __init__(self, adaptee):
        self.adaptee = adaptee
    def request(self):
        return self.adaptee.specific_request()

#class Adapter ,direct
class ClassAdapter(Target):
    def request(self):
        return self.specific_request()

#class Adapter,mixin
class T(object):
    def request(self):
        return self.specific_request()
class AdapterMix(T,Target):
    pass

if __name__ == "__main__":
    c1 = Adapter(Target())
    print c1.request()

    c2 = ClassAdapter()
    print c2.request()

    c3 = AdapterMix()
    print c3.request()
