Hi Susan,

Thanks for your helpful post.

I think you should fix the function

def cleanText(text):
text = text.strip().replace("\n", " ").replace("\r", " ")
text = text.lower()

to include return statement:

def cleanText(text):
text = text.strip().replace("\n", " ").replace("\r", " ")
text = text.lower()
# TODO: add the next line
return text

For me, the original code raises an exception and the fixed code works.
