Program Plan Intro
Logical “and” Operator:
Logical operator combines the results of one or more conditions.
- • The logical “and” is used to evaluate two expressions in order to obtain a single relational result.
- • It returns the Boolean value “True” when both the operands are true, otherwise returns “False”.
- • The first operand is evaluated first and all the side effects are completed before evaluating the logical “and” expression.
- • The second operand is evaluated only if the first operand is “True”.
Syntax for “and” operator:
The syntax for “and” operator is given below:
expression1 and expression2
Logical “or” Operator:
Logical operator combines the results of one or more conditions.
- • The logical “or” is used to evaluate two expressions in order to obtain a single relational result.
- • It returns the Boolean value “True” when one of the operands is “True”. It returns “False” only if both the operands are “False”.
- • The first operand is evaluated and all the effects are completed before it continues to evaluate the logical “or” expression.
- • The second operand is evaluated only if the first operand returns “False”.
Syntax for “or” operator:
The syntax for “or” operator is given below:
Expression1 or expression2
