Challenge: Positive, Negative or ZeroChallenge: Positive, Negative or Zero

Recall the exercise from two chapters back. In that challenge, you crafted an if/else statement to determine if a number was even or odd. Now, let's create another conditional structure that identifies zeros, positive numbers, and negative numbers.

Завдання

Design an if/elif/else statement to assess whether the number num is positive, negative, or zero.

  • If num is negative, print "The number num is negative".
  • If num is positive, print "The number num is positive".
  • If num is 0, print "The number num is zero".

To accomplish this, fill in the blanks (indicated by ___) in the print() functions with the appropriate terms.
