STEP 10: Let's start writing our classify_animal function!

• Remember, this function returns the animal's class as a string. We should create a variable in which to store it.
• In , drag String Variable indented inside classify_animal().
• Change the variable to the left of the = sign from my_var to animal_class.
• Finally, change "This is a string" to "unknown", since we at first don't know the animal's classification.
