>>> a = '你好'
>>> isinstance(a,str)
True
>>> isinstance(a,int)
False

isinstance () and type () the difference:

• type () does not think that is a subclass of parent class type, without regard to inheritance.

• isinstance () will be considered sub-class is a parent class type, consider inheritance.

To determine whether two of the same type recommended isinstance ().
