I'm not getting an index?

I've copied the code and when you run it you are supposed to get an index with a number but when I run this in cmd I don't get any number at all and the line where it should be is blank. Is this code out of date? Or is it some other issue I'm not seeing?

This is the code

from sklearn.datasets import load_iris
iris = load_iris()
print(list(iris.target_names))

from sklearn import tree
classifier = tree.DecisionTreeClassifier()
classifier = classifier.fit(iris.data, iris.target)
print(classifier.predict([[5.1,3.5,1.4,1.5]]))
