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.

Python’s not is a logical operator that inverts the truth value of Boolean expressions and objects. It’s handy when you need to check for unmet conditions in conditional statements and while loops.

Probably the best way is using the operator not: So instead of your code: return False. return True. You could use: There are also two functions in the operator module operator.not_ and it's alias operator.__not__ in case you need it as function instead of as operator:

The Python "not" operator is an essential tool for logical negation in conditions, loops, and expressions. Learning to properly use the "not" Boolean operator lets you write cleaner, more readable code, especially when dealing with Boolean …

Definition and Usage 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.

Jul 23, 2021 · The not keyword is a logical operator. The return value will be True if the statement (s) is not True and the return value will be False if the statement (s) is not False.

Oct 19, 2022 · This operator can be applied in boolean situations like if statements and while loops. It also functions in non-Boolean settings, enabling you to reverse the variables’ truth values.

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:

In this tutorial, we learned how to use the Python not logical operator with boolean and non-boolean operands. The not operator inverts the truth value of its operand, returning True for False operands and False for True operands.

Using the not operator in the Python programming language is simple. Simply place not before any boolean expression to invert its truth value: The not operator returns True since is_off is False. not, in Python, is crucial when you need to reverse a condition's logic. This capability is especially useful in the following programming scenarios:
