How to check variable type in python

There are two ways to view variable types in python:

isinstance() function

can be used to determine the type of a variable. It returns a Boolean value, False or True.

>>>isinstance("123",str)
>>>True
>>>isinstance(123,int)
>>>True
>>>isinstance({'123'},list)
>>>False
>>>isinstance(['123'],list)
>>>True

Like int, float, etc. are all basic variable types. In fact, classes are also a type of variables.

type() function

does not determine the type of the variable, but directly returns the type of the variable

>>>class A():
 ...   pass
 >>>B=A()
 >>>type(B)
<class &#39;A&#39;>
>>>type(A)
<class &#39;type&#39;>
>>>type(A())
<class &#39;A&#39;>
>>>a=2
>>>type(a)
<class &#39;int&#39;>
