Questions and Answers

What is the purpose of the if-elif-else statement in the given code?

  • To demonstrate the use of indentation and colons in Python
  • To print a message based on the relationship between `x` and `y`
  • To convert a numeric grade into a letter grade (correct)
  • To initialize the variables `x` and `y`

What will be the output of the code if the value of grade is 92?

  • B
  • A
  • A- (correct)
  • B+

Which of the following is a correct way to handle an invalid grade value in the if-elif-else statement?

  • Use a separate `if` statement to check for invalid grades
  • Use the `else` clause to handle invalid grades
  • Use a `try-except` block to handle invalid grades
  • All of the above (correct)
