Example of using adapter adapter pattern in Python design pattern programming

Transforms the interface of one class into another interface that the customer wants. Those classes that would otherwise not work together because of incompatible interfaces can work together.
Scenario: You want to reuse some existing classes, but the interfaces are inconsistent with the reuse environment requirements.

Pattern feature: Transforms the interface of a class into another interface that the customer wants.

Classification: Class adapters (through multiple inheritance), object adapters.

To illustrate by example, here's how a user can use a class using an adapter

Class Target:def request ():  print "common request." Class Adaptee (Target): def specificrequest (self):  print "specific request." Class Adapter (Target): def __init__ (Self,ada):  self.adaptee = Ada def Request (self):  Self.adaptee.SpecificRequest () if __name__ = = "__main__": Adaptee = adaptee () adapter = adapter (adaptee) adapter. Request ()

Let's look at a simple adapter example

#encoding =utf-8 # #by Panda #适配器模式 def printinfo (info): Print Unicode (info, ' utf-8 '). Encode (' GBK ') #球员类 class Player ()   : Name = "Def __init__ (self,name): self.name = name def Attack (self,name): Pass def Defense (self): Pass #前锋 class Forwards (Player): def __init__ (self,name): player.__init__ (Self,name) def Attack (self): Printinfo ("Striker%s Offense "% self.name" def Defense (self,name): Printinfo ("Striker%s defensive"% Self.name) #中锋 (target Class) class Center (Player): Def __init   __ (Self,name): player.__init__ (Self,name) def Attack (self): printinfo ("Center%s offense"% self.name) def Defense (self): Printinfo ("center%s defensive"% self.name) #后卫 class Guards (Player): def __init__ (self,name): player.__init__ (self,name) d  EF Attack (self): Printinfo ("defender%s offense"% self.name) def Defense (self): Printinfo ("defender%s Defense"% self.name) #外籍中锋 (to be adapted class) #中锋 class Foreigncenter (Player): name = "Def __init__ (self,name): player.__init__ (Self,name) def foreignattack (s ELF): Printinfo ("Foreign Center%S offense "% self.name" def foreigndefense (self): printinfo ("Foreign center%s defensive"% self.name) #翻译 (Adaptive Class) class Translator (Player): Foreigncenter = None def __init__ (self,name): Self.foreigncenter = Foreigncenter (name) def Attack (self): self.for Eigncenter.foreignattack () def Defense (self): Self.foreignCenter.ForeignDefense () def clientui (): b = Forwards (' Buddy m = Guards (' mcgrady ') ym = Translator (' Yao ') b.attack () m.defense () ym.
