Apr 7, 2025 · The not keyword in Python is a logical operator used to obtain the negation or opposite Boolean value of an operand. It is a unary operator, meaning it takes only one operand and returns its complementary Boolean value. For example, if False is given as an operand to not, it returns True, and vice versa; How to Use Not Operator in Python?

Python’s not operator allows you to invert the truth value of Boolean expressions and objects. You can use this operator in Boolean contexts, such as if statements and while loops. It also works in non-Boolean contexts, which allows you to invert the truth value of your variables.

Python Keywords. Return True if the statement is not True: The not keyword is a logical operator. The return value will be True if the statement (s) are not True, otherwise it will return False.

In Python, the not keyword is a logical operator that inverts the truth value of the expression returning True or False. It’s also used in negated membership tests with the not in operator and negated identity checks with the is not the operator. Here’s a quick example to demonstrate how to use the not keyword:

Here’s the syntax: if condition: # code to execute if condition is True Let’s see a practical example: ... Conditional Expressions (Ternary Operators) Python also supports a compact way to write simple if-else statements called conditional expressions: # Syntax: value_if_true if condition else value_if_false state = "NY" tax_rate = 0.08 if ...

The `not` operator in Python is a logical operator used to invert the truth value of a Boolean expression. It turns `True` into `False` and `False` into `True`. This operator is particularly useful for simplifying and enhancing conditional logic in your code.
