'''
# mro列表 :通过c3算法,把所有的继承关系按照列表的顺序呈现.
# 语法:
类.mro() => 继承顺序列表
[
<class '__main__.Children'>,
<class '__main__.Man'>,
<class '__main__.Woman'>,
<class '__main__.Human'>,
<class 'object'>
]
super 就是默认按照mro列表的顺序,依次调用
用于解决多继承调用顺序混乱的问题
'''

res = issubclass(Children,Man)
res = issubclass(Children,Human)
# 满足一个条件,即返回真
res = issubclass(Children,(Man,Woman))
print(res)
# 判断对象的类型 [有血缘关系即可] isinstance
res = isinstance(obj,Children)
res = isinstance(obj,Man)
res = isinstance(obj,(Human,Woman))
