How to check if a variable is None in Python?

Answer   Submitted by Answiki on 02/26/2022 at 06:40:31 PM UTC

In Python, you can use the is operator to check for NoneType:

if (x is None):
    printf ('x is NoneType')

In the same way, you can check if the variable is not NoneType:

if (x is not None):
    printf (x)
