Adapter Design Pattern in Python

""" Convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn't otherwise because of incompatible interfaces. """ import abc class Target(metaclass=abc.ABCMeta): """ Define the domain-specific interface that Client uses. """ def __init__(self): self._adaptee = Adaptee() @abc.abstractmethod def request(self): pass class Adapter(Target): """ Adapt the interface of Adaptee to the Target interface. """ def request(self): self._adaptee.specific_request() class Adaptee: """ Define an existing interface that needs adapting. """ def specific_request(self): pass def main(): adapter = Adapter() adapter.request() if __name__ == "__main__": main()
