python中多态的实例解析（详细）

class Human(object):  # 父类 ：创建“人”类

    def __init__(self):

           print('Ill pound the code and buy you a bag')  # 我会敲打码，给你买包包

class Man(Human):  # 1）子类1 创建“男人”类

    def __init__(self):

           print('In hs, we should have the knowledge to drink wine.The President up, the kitchen down')  # 在衡水，要文武双全，有知识，会喝酒；上的总裁，下的厨房

class Woman(Human):# 2）子类2 创建“女人”类

print('human:')

h = Human()

print('man:')

m = Man()

print('woman:')

w = Woman()  # 分别对 人类、男人类、女人类创建一个变量h、m、w

print(isinstance(h,Human))#isinstance举例

print(isinstance(m,Man))

print(isinstance(m,Human))  #  分别判断h是人类吗、m是男人类吗、m是人类吗，输出结果全部为是。

#输出结果是：

# human:

# Ill pound the code and buy you a bag

# man:

# In hs, we should have the knowledge to drink wine.The President up, the kitchen down

# woman:

# If a man loves me, I dont care if he has a house or a
