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.

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?

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.

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 …

Oct 19, 2022 · not is a unary operator which means it takes only one input value. It can be used with any boolean expression or Python object. Let’s see how the not operator in Python works with the different types of conditional statements we have. print("num is an odd number") print("num is an even number") Output: Here, num%2 i.e. 25%2 equals 1 and not 0.

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:

Jan 26, 2025 · The `not` operator in Python allows developers to reverse the truth value of a given expression. This seemingly simple operator has far-reaching implications and can be used in a variety of scenarios to write more robust and flexible code.

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:

Jul 4, 2020 · ‘not’ is a case–sensitive keyword and only returns Boolean values (True or False). It returns the reverse of the original result, i.e., if the first output was coming to be True, ‘not’ will convert it into False and vice versa. Let’s understand it with an example, and then we will discuss it in detail. Without ‘not’’- print(x) . print(y) .
