Changed it like who said? I'm assuming myself, but with no context you
can't always tell. Also, stating "didn't work" is often useless to us.
What didn't work? Why didn't it work? Here it's obvious, you're
throwing away the return value from your function call. Either save the
return value and print it or add the function call directly to your
original print call.
My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
