Python method to determine whether it is an integer:

1. Use the type() function to determine

type ()Function syntax:

type(object)
type(name, bases, dict)

type() function returns the type of the object if you only have the first parameter, and the three parameters return the new type object.

Example:

>>> type(1)
<type &#39;int&#39;>

2. Use the isinstance() function to determine

isinstance() Syntax of the method:

isinstance(object, classinfo)

If the type of the object is the same as the type of parameter two (classinfo), it returns True, otherwise it returns False.

Example:

>>>a = 2
>>> isinstance (a,int)
True
