operator in CLogical NOT is denoted by exclamatory characters (!), it is used to check the opposite result of any given test condition.If any condition's result is non-zero (true), it returns 0 (false) and if an

A logical operator in computer science refers to a fundamental operation that performs logical calculations on two or more values and produces a result based on the truth values of the inputs. Some examples of logical operators include AND, OR, XOR, and NOT. These operators are used in electr...

The ___ operator is used to negate a Boolean expression in Python (logical NOT). The ___ operator is used for bitwise negation (flip the bits) in Python. The expression not True will result in ___. The result of the bitwise negation of 5 (in binary: 0101) will be ___. ...

The&operator always evaluates both operands. When the left-hand operand evaluates tofalse, the operation result isfalseregardless of the value of the right-hand operand. However, even then, the right-hand operand is evaluated. In the following example, the right-hand operand of the&opera...
Execute code based on a condition using the logical not operator in the context of anifloop. Create a logical variableA. A = false; UseAto write an if/else code block. Wrap the if/else block in aforloop so that it executes four times. ...

NOT has the highest precedence, so not c is evaluated first: not c isfalsenow b and c mean true and false AND operator will evaluated first, then true and false become false Now, the OR operator will be evaluated, and then a or false, which means False or False, returns False, so ...
