If/Elif/Else

If we want to add one additional cases in the problem we need to use elif statement.

If you want to go deeper into if/elif/else statements, we have a course with more tasks to learn more about if/else blocks.

Let's add an additional case to the problem from the previous task.

Task

Do you recall analysts from the if-else chapter? They decided to set new discounts. If the price is bigger than 25, the discount will be 25%; if the price is lower than or equals 25, the discount will be 15%. Otherwise, 5%.

Set the condition if the price is bigger than 25.
Set the 25% discount if the price is greater than 25.
Set the condition if the price is lower than or equals 25 or greater the 10.
Set the 15% discount in case of the 3. item. !
Otherwise, set the 5% discount.
Print the price_upd.

! To set the 15% discount use value * 0.85

Task

Set the condition if the price is bigger than 25.
Set the 25% discount if the price is greater than 25.
Set the condition if the price is lower than or equals 25 or greater the 10.
Set the 15% discount in case of the 3. item. !
Otherwise, set the 5% discount.
Print the price_upd.

! To set the 15% discount use value * 0.85
