1. 代码示例与功能实现

1.1 《Dead Parrot Sketch》实现

以下是《Dead Parrot Sketch》的实现代码：

class Actor:
    def line(self): print self.name + ':', repr(self.says( ))
class Customer(Actor):
    name = 'customer'
    def says(self): return "that's one ex-bird!"
class Clerk(Actor):
    name = 'clerk'
    def says(self): return "no it isn't..."
class Parrot(Actor):
    name = 'parrot'
    def says(self): return None
class Scene:
    def __init__(self):
        self.clerk    = Clerk( )
        self.customer = Customer( )
        self.subject  = Parrot( )
    def action(self):
        self.customer.line( )
        self.clerk.line( )
        self.subject.line( )

此代码通过定义不同的类，模拟了一个场景，其中 Actor </
