Python implements the interface class in two ways + email reminder + Dynamic Import Module + reflection (refer to Django middleware source code)

Two ways to implement an interface class

 from Import Abcmeta  from Import Abstractmethod class Basemessage (metaclass=abcmeta):    @abstractmethod    def  Send (Self,subject,body,to, Name):        Pass

Way Two

class Basemessage (object):     def Send (self, subject, body, to, name):         Raise Notimplementederror (' not implemented Send method ')

Email alerts
