There seems to be a bug in the code on the keys returned? It throws the error:

<ipython-input-4-2ade2396697d> in predict_example(example, tree)
216 def predict_example(example, tree):
217 question = list(tree.keys())[0]
--> 218 feature_name, comparison_operator, value = question.split(" ")
219
220 # ask question

ValueError: too many values to unpack (expected 3)
