What is the significance of logical operators in python
Operators are used to perform operations on values and variables. These are the special symbols that carry out arithmetic and logical computations. The value the operator operates on is known as Operand.
Logical operatorsIn Python, Logical operators are used on conditional statements (either True or False). They perform Logical AND, Logical OR and Logical NOT operations.
Logical AND operatorLogical operator returns Example #1:
Output: The numbers are greater than 0 Atleast one number is not greater than 0 Example #2:
Output: Atleast one number has boolean value as False Note: If the first expression evaluated to be false while using and operator, then the further expressions are not evaluated. Logical or operatorLogical or operator returns True if either of the operands is True. Example #1:
Output: Either of the number is greater than 0 No number is greater than 0
Output: Atleast one number has boolean value as True Note: If the first expression evaluated to be True while using or operator, then the further expressions are not evaluated. Logical not operatorLogical not operator work with the single boolean value. If the boolean value is Example:
Output: 10 is divisible by either 3 or 5 Order of evaluation of logical operatorsIn the case of multiple operators, Python always evaluates the expression from left to right. This can be verified by the below example. Example:
Output: Method called for value: -1 Method called for value: 5 Atleast one of the number is positive |
