bookChallenge: Odd and Even

Let's tackle another practice task!

Task

You're provided with a number labeled num. Using if/else, display the message:

  • "The number num is odd" if num is odd.
  • "The number num is even" if num is even.

In the print() functions, fill in the ___ with the appropriate descriptor ('odd' or 'even'). Tip: A number is considered even if, when divided by 2, the remainder (using the % operator) is 0.

Note

In Python, the % operator is used as the modulo operator, which returns the remainder after dividing one number by another. For example, 5 % 2 would return 1, since 2 goes into 5 twice with a remainder of 1.
