How to check if a value in Python is an integer

To check if a value in Python is an integer, you can use the isinstance() function to check if the value is an instance of the int class. Here’s an example:

x = 10
if isinstance(x, int):
    print("x is an integer")
else:
    print("x is not an integer")

This will output “x is an integer”. If the value of x was a string, for example, it would output “x is not an integer”.

Keep in mind that in Python 3.x, there is no separate long type as there was in Python 2.x. In Python 3.x, all integers are represented as int.
