Python的多态性实例分析

本文实例讲述了Python的多态性。分享给大家供大家参考。具体如下：

    #!/usr/bin/env python
    # polymorphism in python
    #
    class base(object):
      """base class"""
      def __init__(self, name):
        self.name = name
      def printest(self):
        print "base class: ", self.name
    class subclass1(base):
      """sub class 1"""
      def printest(self):
        print "sub class 1: ", self.name
    class subclass2(base):
      """sub class 2"""
      def printest(self):
        print "sub class 2: ", self.name
    class subclass3(base):
      """sub class 3"""
      pass
    def testFunc(o):
      o.printest()
    if __name__ == "__main__":
      testFunc(subclass1("1"))
      testFunc(subclass2("2"))
      testFunc(subclass3("3"))

希望本文所述对大家的Python程序设计有所帮助。
