What is the result of not true or false in Python?
The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True , while the expression 0 == 1 is False ….The not Boolean Operator.
What is == in Python?
The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and != , except when you’re comparing to None .
How do you compare two Boolean values in Python?
When you compare two values, the expression is evaluated and Python returns the Boolean answer:
- print(10 > 9)
- Print a message based on whether the condition is True or False :
- Evaluate a string and a number:
- Evaluate two variables:
- The following will return True:
- The following will return False:
- class myclass():
What is Boolean expression with example?
A boolean expression is an expression that results in a boolean value, that is, in a value of either true or false . The println statement will be executed if wet and cold are both true, or if poor and hungry are both true. Boolean expressions are most often used as conditions (as in the examples above).

|It is an assignment operator.||It is a relational or comparison operator.|
|It is used for assigning the value to a variable.||It is used for comparing two values. It returns 1 if both the values are equal otherwise returns 0.|
Which is not equal to a comparison operator?

|=||Equals||True if the items are equal|
|≠||Not Equal To||True if the items are not equal|
What are the possible values of == operator?
This means that each bit can be one of 4 values: 0,1,x,z. With the “case equality” operator, === , x’s are compared, and the result is 1. With == , the result of the comparison is not 0, as you stated; rather, the result is x, according to the IEEE Std (1800-2009), section 11.4

What are basic operators?
An operator is a special symbol or phrase that you use to check, change, or combine values. For example, the addition operator ( + ) adds two numbers, as in let i = 1 + 2 , and the logical AND operator ( && ) combines two Boolean values, as in if enteredDoorCode && passedRetinaScan .
What is an operator give example?
1. In mathematics and sometimes in computer programming, an operator is a character that represents an action, as for example x is an arithmetic operator that represents multiplication.
