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.

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.

Dec 18, 2019 · So I know python has the not operator, but how does the not() function come into play? From some simple testing it appears that it has the signature of not(args[]), while at the same time not acting entirely like a normal function.

You can use the "not" operator in Python to simplify logical conditions. As a simple example, let us check if a number is not in range: num = 15 if not (10 <= num <= 20): print("Number is out of the specified range.")

Oct 19, 2022 · We shall learn about Python’s not operator in this tutorial. It is used to get the negation of a value, i.e. it allows us to invert the truth value of a given boolean expression. This operator can be applied in boolean situations like if statements and while loops.

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.

Jan 26, 2025 · One such essential logical operator is the not operator. 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 …

Sep 7, 2023 · In its simplest form, the ‘not’ keyword in Python is used to reverse the truth value of the operand it precedes. If the operand is True, ‘not’ will return False, and if the operand is False, ‘not’ will return True. This is a fundamental aspect of Python’s logical operations. Here is a basic example of using the ‘not’ keyword:

Oct 8, 2023 · In Python not is a built-in operator and it cannot be overloaded. The brackets are redundant. So, no matter what your intention is in using that syntax, not(x) would only serve to misdirect someone with a normal understanding of Python. This is not pythonic.
