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:
