python判断变量类型

1. isinstance()

>>> x = isinstance("hello",(float,str,int,dict,list,tuple,bool))
>>> x
True

 

>>> x=(1,2,3,4)
>>> isinstance(x,dict)
False
>>> isinstance(x,tuple)
True
>>> isinstance(x,list)
False
>>> isinstance(x,int)
False
>>> isinstance(x,str)
False
>>> 
>>> isinstance(x,(int,str,dict))
False
>>> isinstance(x,(int,str,dict,tuple))
True

2. type()

>>> x = isinstance("hello",(float,str,int,dict,list,tuple))
>>> x
True
>>> print(type(x))

>>> type(x)==bool
True
>>> type(x)==int 
False
