If not true in Python | Example code

If not true means the ‘not operator‘ is used in the if statements in Python. The ‘not’ is a Logical operator in Python that will return True if the expression is False.

if not var

If var is True, then not will evaluate as false, otherwise, True.

Example If not true in Python

Simple Python not-operator example with if statement.

x = 10

if not x > 0:
    print("x is not greater then 0")
    print("x is greater then 0")

Output: As x>0 is False, so not-operator evaluated as True.

Python example if not with ‘in’

The elements that evaluated False as using ‘not’ did not display in the console.

a_List = [5, 10, 15, 20, 25, 30]

for a in a_List:
    if not a in (10, 25):
        print("List Item: ", a)
