How to do not in python
|
The ‘not’ is a Logical operator in Python that will return True if the expression is False. The ‘not’ operator is used in the if statements. For example: if not x If x is True, then not will evaluate as false, otherwise, True. Other logical operators: The and operator | OR operator I will show you a few examples to make things clearer regarding how to use the
not operator in the coming section. In the following example, a variable x is assigned a value 10. The ‘not’ is used in the if statement as follows: if not x > 10: See the code and result.
#A demo of Python 'not' operator x=10 ifnotx>10: print("not retured True") else: print("not retured
False")  As x>10 is False, so not operator evaluated as True, thus the if statement is True and code inside the if statement executed. See next example that will make things even clearer. How not operator works?In this demo, the x is used as follows with not operator: See online demo and code
The expression not x means if x is True or False. In Python, if a variable is a numeric zero or empty, or a None object then it is considered as False, otherwise True. In that case, as x = 10 so it is True. As x is True, so not operator evaluated as False and else part executed. See the same example below where the value of x = 0. See online demo and code
A Python not with ‘in’ exampleIn this example, I will show you how to use the ‘not’ operator with ‘in’. For that, a numeric list of six items is created. This is followed by using a for loop to iterate through the list elements and display their values. After that, an if statement is used to omit certain numbers to be displayed. There, the not operator is used with the ‘in’ as follows: See online demo and code
You see, the items that evaluated False as using ‘not’ did not display.

The syntax for an if statement with the not logical operator is: if not condition: # Do something... In this example, condition could be a Boolean expression or any Python object that makes sense.
How do you use the not function in Python?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 .
What is the != operator in Python?Not Equal Operator in Python
If the values compared are equal, then a value of true is returned. If the values compared are not equal, then a value of false is returned. != is the symbol we use for the not equal operator.
Is not or != In Python?In Python != is defined as not equal to operator. It returns True if operands on either side are not equal to each other, and returns False if they are equal. Whereas is not operator checks whether id() of two objects is same or not.
