If-Else Statement

When we need to execute the block of statements either when the condition is true or when the condition is false, we must use the if-else statement.

If the condition, which is a Boolean expression evaluates to True, then the statements inside the 'if' body will be executed. And if the condition evaluates to false, then the statements inside the 'else' body will be executed.
