41 isinstance

判断object是否为类classinfo的实例，是返回true

In [1]: class Student():
   ...:     def __init__(self,id,name):
   ...:         self.id = id
   ...:         self.name = name
   ...:     def __repr__(self):
   ...:         return 'id = '+self.id +', name = '+self.name

In [2]: xiaoming = Student(id='001',name='xiaoming')

In [3]: isinstance(xiaoming,Student)
Out[3]: True
