#指挥者
class PersonDirector():

def __init__( self , pb):
self .pb = pb
def CreatePereson( self ):
self .pb.BuildHead()
self .pb.BuildBody()
self .pb.BuildArm()
self .pb.BuildLeg()
def clientUI():
pb = PersonThinBuilder()
pd = PersonDirector(pb)
pd.CreatePereson()
pb = PersonFatBuilder()
pd = PersonDirector(pb)
pd.CreatePereson()
return
if __name__ = = '__main__' :
clientUI();

运行结果:
构建瘦子的头
构建瘦子的身体
构建瘦子的手
构建瘦子的脚
构建胖子的头
构建胖子的身体
构建胖子的手
构建胖子的脚
希望本文所述对大家Python程序设计有所帮助。
