模式特点：将一个类的接口转换成为客户希望的另外一个接口。

分类：类适配器（通过多重继承）、对象适配器。

来通过例子说明，下面是用户通过适配器使用一个类的方法

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()

我们再来看一个简单的Adapter例子
