For example, if you want to test if a variable is not equal to a certain value, you can use the not operator to invert the condition. The not operator is often used in conjunction with if statements to test for the opposite of a condition. The not operator is used to invert the value of x, so the output is False.Įxample 2 of Python not operator: Using if statements In this section of the blog, we will discuss various examples of python not operator with code and implementations.Įxample 1 of Python not Operator: Inverting the inputīelow is the implementation of the above-mentioned example. You can understand the python not operator by the following table: If the expression returns In Python, you write not x to apply the not operator to the argument x.ĭepending on the meaning of the input, the not operator in Python can return either Yes or False. To put it another way, the processor only takes one input. The not operator is the sole unary Boolean operator available in Python. Similar to the not gate used in digital electronics, it serves the same purpose. Not will assess a check as False if it is True and vice versa.Īlong with the AND and OR operators, the not operator in Python is regarded as one of the language’s fundamental operators. You must then specify an expression or a variable that is linked to a boolean result. The Python not operator applies logical negative to a Boolean statement. Here is an example: not xĮxplanation of the syntax of python not operator It is represented by the keyword not, followed by the expression that you want to invert. The syntax for the not operator is simple. If the expression is true, not return false, and if the expression is false, not return true. When used with a Boolean expression, the not operator returns the opposite of the expression’s value. It is a unary operator, which means it operates on a single operand. The not operator is a logical operator in Python that is used to invert the value of a Boolean expression. | bool(x) -> bool What is the Not Operator in Python? * Code Implementation Python program to show that boolean objects are a subclass of the int object Checking if bool is a subclass of int print(issubclass(bool, int)) Getting details of bool The Python bool data type is a subclass of the Python int object. These Boolean elements and operators are useful in programming because they allow you to choose the path your programs should take. It also defines the Boolean operations AND, OR, and NOT. George Boole invented Boolean algebra, which uses True and False values. While moving further in this blog we will take a closer at the not operator in Python, how it works, and how it can be used in your code. Python not operator allows you to negate a boolean expression. Python not operator is one of the many operators provided by a python that can be used to manipulate and compare values in your code.
