Turtles can determine whether a number is above or below another number. Let's write a program that asks how old you are:

Advanced: In the example above you'll see there are try: and except:. These lines try to run code that comes after try:, and if any errors happen, do what's in the except: section. This is how Tina knows whether you put in a real number like 15. This is how real programmers change the behavior of programs based on any errors that might come up.
