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 operands return “False”. Syntax for “or” operator: The syntax for “or” operator is given below: Expression1 or expression2

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 operands return “False”.

Syntax for “or” operator:

The syntax for “or” operator is given below:

Expression1 or expression2
