Flashcards

`if-elif-else` purpose

Converts a numeric grade into a corresponding letter grade based on predefined ranges.

Handling Invalid Grade

To handle invalid input by checking if the grade is outside the acceptable range (0-100) and providing an appropriate error message.

Colon (:) Purpose

To define the block of code that should be executed if a certain condition is true.

Multiple Conditions (`or`)

Used to check multiple conditions. It allows for a more compact way to express multiple conditions that need to be checked.
