The not Operator Returning the Opposite

In this lesson, we’ll explore the not operator more closely, expanding on its earlier introduction.

The not operator returns the opposite of a Boolean value.

It is primarily used with conditional statements to handle cases where a condition is false or negated.


Using the not Operator​

The not operator returns False if the value on its right is True, and True if the value is False.

Using the not Operator
is_logged_in = False

# Prints True, the opposite of False
print("not is_logged_in:", not is_logged_in)

if not is_logged_in:
    print("Login is required.")
